# Architecture Pipeline Kazeia
|
||||||
|
|
||||||
|
*Version 2.0 — 28 mars 2026*
|
||||||
|
|
||||||
|
## Principe
|
||||||
|
|
||||||
|
Le pipeline Kazeia est **modulaire** : STT et TTS sont indépendants et échangent uniquement du texte avec une chaîne de processeurs pluggables.
|
||||||
|
|
||||||
|
```
|
||||||
|
┌─────────┐ ┌──────────────────────────┐ ┌─────────┐
|
||||||
|
│ STT │────→│ PROCESSOR CHAIN │────→│ TTS │
|
||||||

|
||||||
|
suspend fun load(modelPath: String?)
|
||||||
|
fun isLoaded(): Boolean
|
||||||

```
|
||||||
|
|
||||||
|

|
||||||
|
fun stop()
|
||||||
|
fun release()
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Implémentations :
|
||||||
|
| Classe | Backend | Latence | Clonage voix |
|
||||||
|
|--------|---------|---------|-------------|
|
||||||
|
| `AndroidTtsEngine` | Google TTS | ~200ms | Non |
|
||||||
|
| `ChatterboxTtsEngine` | ONNX CPU/NPU | ~3-10s | Oui |
|
||||||
|
|
||||||
|
### MessageProcessor (Middleware)
|
||||||
|
```kotlin
|
||||||
|
interface MessageProcessor {
|
||||||
|
val name: String
|
||||||
|
suspend fun initialize()
|
||||||
|
fun isReady(): Boolean
|
||||||
|
suspend fun process(input: String, context: ConversationContext): ProcessorResult
|
||||||
|
fun release()
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Implémentations :
|
||||||
|
| Classe | Rôle | Priorité |
|
||||||
|
|--------|------|----------|
|
||||||
|
| `VoiceCommandProcessor2` | Intercepte les commandes vocales | 1 (premier) |
|
||||||
|
| `LlmProcessor` | Génère des réponses via LLM | 2 |
|
||||||
|
| `EchoProcessor` | Répète l'input (fallback/test) | 3 |
|
||||||
|
| *(Future)* `EmotionProcessor` | Détecte l'émotion de la voix | 1.5 |
|
||||||
|
| *(Future)* `RagProcessor` | Enrichit avec des documents | 1.5 |
|
||||||
|
| *(Future)* `DiarizationProcessor` | Identifie le locuteur | 1 |
|
||||||
|
|
||||||
|
### Chaîne de traitement
|
||||||
|
|
||||||
|
Les processeurs sont exécutés **dans l'ordre**. Le premier qui retourne `shouldContinueChain = false` termine la chaîne.
|
||||||
|
|
||||||
|
```
|
||||||
|
Input: "Bonjour, comment vas-tu ?"
|
||||||
|
→ VoiceCommandProcessor2: pas de commande → continue
|
||||||
|
→ LlmProcessor: "Je vais bien, comment puis-je t'aider ?" → done
|
||||||
|
Output: "Je vais bien, comment puis-je t'aider ?"
|
||||||
|
|
||||||
|
Input: "stop"
|
||||||
|
→ VoiceCommandProcessor2: commande STOP_LISTENING → done (shouldSpeak=false)
|
||||||
|
Output: (arrête l'écoute)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Ajouter un nouveau processeur
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
class MonNouveauProcessor : MessageProcessor {
|
||||||
|
override val name = "MonProcesseur"
|
||||||
|
|
||||||
|
override suspend fun process(input: String, context: ConversationContext): ProcessorResult {
|
||||||
|
// Traiter l'input
|
||||||
|
val enrichedInput = "[$emotion] $input"
|
||||||
|
|
||||||
|
return ProcessorResult(
|
||||||
|
responseText = "",
|
||||||
|
shouldContinueChain = true, // passe au processeur suivant
|
||||||
|
metadata = mapOf("emotion" to "triste")
|
||||||
|
)
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
// Ajout au pipeline
|
||||||
|
pipeline.addProcessor(MonNouveauProcessor())
|
||||||
|
```
|
||||||
|
|
||||||
|
## ConversationContext
|
||||||
|
|
||||||
|
Le contexte est partagé entre tous les processeurs :
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
data class ConversationContext(
|
||||||
|
val history: List<ChatMessage>, // historique conversation
|
||||||
|
val metadata: MutableMap<String, Any>, // données partagées
|
||||||
|
val language: String, // "fr"
|
||||||
|
val speakerId: String?, // identification locuteur
|
||||||
|
val emotion: String?, // émotion détectée
|
||||||
|
val sessionId: String // identifiant session
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
Les processeurs peuvent lire et écrire dans `metadata` pour communiquer entre eux.
|
||||||
|
|
||||||
|

# Rapport technique — Avatar 3D pour Kazeia
|
||||||
|
## Face cloning, voice cloning, lip sync temps réel
|

|
## 1. Vision
|
||||||
|
|
||||||
|
Kazeia est un compagnon de support émotionnel. L'avatar 3D donne un visage à ce compagnon :
|
||||||
|
|
||||||
|
- **Mode enfant** : personnage stylisé (ours en peluche, mascotte) avec expressions et lip sync
|
||||||
|
- **Mode ado/adulte** : visage humain photoréaliste reconstruit depuis une photo/vidéo de la personne ayant donné son consentement (thérapeute, proche, éducateur...)
|
||||||
|
|
||||||
|
L'avatar parle avec la voix clonée de cette même personne (voice cloning Qwen3-TTS), créant une expérience cohérente visage + voix.
|
||||||

## 4. Protocole de capture — Séquence unique (~60 secondes)
|
||||||
|
|
||||||
|
### Principe
|
||||||
|
|
||||||
|
Une seule séquence de capture sert 3 objectifs :
|
||||||
|
1. **Preuve légale** de consentement (vidéo horodatée)
|
||||||
|
2. **Clonage vocal** (extraction x-vector depuis l'audio)
|
||||||
|
3. **Création avatar** (géométrie 3D, texture, calibration expressions)
|
||||||
|
|
||||||
|
### Phase 1 — Rotation guidée (20s)
|
||||||
|
|
||||||
|
L'utilisateur tourne lentement la tête, guidé par un overlay face tracking (MediaPipe Face Mesh, 468 landmarks).
|
||||||
|
|
||||||
|
```
|
||||||
|
Captures automatiques aux angles détectés :
|
||||||
|
|
||||||
|
④ ② ① ③ ⑤
|
||||||
|
60° gauche 30° G FACE 30° D 60° droite
|
||||||
|
```
|
||||||
|
|
||||||
|
- 5-7 photos **pleine résolution** (8-16 MP caméra frontale)
|
||||||
|
- Expression **neutre** demandée
|
||||||
|
- Pas de vidéo — photos nettes sans motion blur
|
||||||
|
- Face tracking valide l'angle et la netteté avant déclenchement
|
||||||
|
|
||||||
|
**Données extraites** : géométrie 3D (multi-view FLAME fitting), texture UV côtés
|
||||||
|
|
||||||
|
### Phase 2 — Vidéo de consentement (15s)
|
||||||
|
|
||||||
|
Texte affiché en mode prompteur. L'utilisateur lit face caméra :
|
||||||
|
|
||||||
|
> *"J'autorise l'application Kazeia à utiliser mon visage et ma voix, dans le cadre exclusif de cette application, pour créer mon avatar personnel."*
|
||||||
|
|
||||||
|
Formulation choisie pour :
|
||||||
|
- Durée ~6s (minimum pour x-vector fiable : 5s)
|
||||||
|
- Phonèmes variés (voyelles : a/o/i/u/e, consonnes : k/z/p/l/v/d/m)
|
||||||
|
- Clarté juridique (cadre exclusif, avatar personnel)
|
||||||
|
|
||||||
|
**Données extraites** :
|
||||||
|
- **Audio WAV 16kHz** → extraction x-vector (1024 floats) pour voice cloning Qwen3-TTS
|
||||||
|
- **Preuve légale** → vidéo horodatée, chiffrée, stockée sur l'appareil
|
||||||
|
- **Frames vidéo** (~450 frames à 30fps) → sélection automatique des meilleurs frames :
|
||||||
|
- Frame neutre → texture frontale haute résolution supplémentaire
|
||||||
|
- Frames bouche ouverte → calibration visèmes personnalisés
|
||||||
|
- Frames sourire naturel → calibration blendshape sourire
|
||||||
|
|
||||||
|
### Phase 3 — Expressions guidées (10s)
|
||||||
|
|
||||||
|
5 expressions demandées rapidement, toujours frontal :
|
||||||
|
|
||||||
|
| # | Expression | Ce qu'elle calibre |
|
||||||
|
|---|-----------|-------------------|
|
||||||
|
| 1 | Neutre | Référence de repos |
|
||||||
|
| 2 | Sourire (bouche fermée) | Commissures, joues, pommettes |
|
||||||
|
| 3 | Bouche ouverte ("ah") | Mâchoire, lèvres intérieures |
|
||||||
|
| 4 | Sourcils levés | Front, paupières supérieures |
|
||||||
|
| 5 | Yeux fermés | Paupières, cils |
|
||||||
|
|
||||||

**Données extraites** : blendshapes personnalisés (pas les génériques FLAME)
|
||||||
|
|
||||||
|
### Phase optionnelle — Gros plan iris (5s)
|
||||||
|
|
||||||
|
- Capture rapprochée d'un oeil
|
||||||
|
- Couleur et motif de l'iris pour des yeux réalistes
|
||||||
|
- Les yeux sont le premier point de focalisation du regard
|
||||||
|
|
||||||
|
### Conditions de capture
|
||||||
|
|
||||||
|
- **Éclairage** : diffus, face à une fenêtre, pas de soleil direct ni flash
|
||||||
|
- **Fond** : neutre (mur uni) pour faciliter la segmentation
|
||||||
|
- **Position** : stable, tablette posée ou tenue à bout de bras
|
||||||
|
- **Même lumière** pour toutes les phases (cohérence texture)
|
||||||
|
|
||||||
|

## 5. Pipeline de reconstruction 3D
|
||||||
|
|
||||||
|
### 5.1 Géométrie — FLAME multi-view fitting
|
||||||
|
|
||||||
|
```
|
||||||
|
5-7 photos angles + frames vidéo
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
DECA / EMOCA (ResNet-50 backbone, ~25M params)
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
Paramètres FLAME :
|
||||||
|
├── 300 shape params (identité : nez, mâchoire, pommettes...)
|
||||||
|
├── 50 expression params (blendshapes)
|
||||||
|
└── Pose (rotation tête)
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
Mesh FLAME brut : ~5K vertices
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
Subdivision Catmull-Clark (2 passes)
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
Mesh final : ~80K vertices, topology régulière
|
||||||
|
```
|
||||||
|
|
||||||
|
- DECA inference : ~200ms sur GPU Adreno ou NPU (one-shot, une seule fois)
|
||||||
|
- Multi-view fitting améliore significativement vs single-image : profondeur du nez, mâchoire, pommettes
|
||||||
|
- La subdivision est offline (une fois) — ne rajoute pas de coût au rendu
|
||||||
|
|
||||||
|
### 5.2 Texture — Projection multi-vue + super-résolution
|
||||||
|
|
||||||
|
```
|
||||||
|
5-7 photos angles
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
Projection UV par vue
|
||||||
|
(chaque pixel photo → coordonnée UV sur le mesh)
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
Blending multi-vue (pondéré par angle de vue)
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
Texture UV 2048×2048 (données directes ~90%)
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
Inpainting zones manquantes (<10% : dessous menton, intérieur oreilles)
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
Super-résolution (Real-ESRGAN ou équivalent)
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
Texture finale 4096×4096
|
||||||
|
```
|
||||||
|
|
||||||
|
Cartes additionnelles pour le photoréalisme :
|
||||||
|
- **Normal map** : détail des pores (halluciné par ML depuis la texture diffuse, e.g. DECA detail map)
|
||||||
|
- **Roughness/specular map** : zones brillantes (nez, front) vs mates (joues)
|
||||||
|
- **Subsurface scattering** : paramètres peau génériques (difficile à capturer depuis tablette)
|
||||||
|
|
||||||
|
### 5.3 Blendshapes personnalisés
|
||||||
|
|
||||||
|
```
|
||||||
|
5 photos expressions + frames vidéo parole
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
DECA/EMOCA par frame → 50 expression params
|
||||||
|
│
|
||||||

|
||||||
|
Optimisation : ajuster les bases FLAME pour coller
|
||||||
|
au visage spécifique (sourire de cette personne,
|
||||||
|
pas le sourire "moyen" FLAME)
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
52 blendshapes ARKit-compatibles personnalisés
|
||||||
|
```
|
||||||
|
|
||||||
|
Mapping FLAME → ARKit quasi 1:1 :
|
||||||
|
- `jawOpen`, `mouthClose`, `mouthFunnel`, `mouthPucker`, `mouthLeft/Right`
|
||||||
|
- `eyeBlinkLeft/Right`, `browDownLeft/Right`, `browInnerUp`
|
||||||
|
- `cheekPuff`, `cheekSquintLeft/Right`
|
||||||
|
- etc.
|
||||||
|
|
||||||
|
### 5.4 Yeux
|
||||||
|
|
||||||
|
- Iris : texture extraite du gros plan (ou frame vidéo haute-res)
|
||||||
|
- Sclera : blanc procédural avec veinules subtiles
|
||||||
|
- Cornée : reflet spéculaire procédural (point lumineux)
|
||||||
|
- Humidité : couche transparente réflective
|
||||||
|
- **Animation** : saccades oculaires aléatoires, suivi regard (optionnel)
|
||||||
|
|
||||||
|
### 5.5 Cheveux
|
||||||
|
|
||||||
|
Approche pragmatique pour la v1 :
|
||||||
|
- **Carte alpha** (billboard cards) suivant la forme détectée
|
||||||
|
- Pas de rendu strand-level (trop coûteux, pas nécessaire pour un cadrage visage)
|
||||||
|
- Couleur extraite de la photo
|
||||||
|
- Alternative : cadrage serré (front → menton) qui évite le problème
|
||||||
|

|
## 6. Rendu temps réel
|
||||||
|
|
||||||
|
### 6.1 Unity as a Library (UaaL)
|
||||||
|
|
||||||
|
Unity embarqué dans l'app Android native via UaaL :
|
||||||
|
- Export Android AAR depuis Unity
|
||||||
|
- `UnityPlayerActivity` lancée depuis l'app Kotlin
|
||||||
|
- Communication bidirectionnelle : `UnitySendMessage` (Java→C#) et `AndroidJavaObject` (C#→Java)
|
||||||
|
|
||||||
|
Contraintes :
|
||||||
|
- Unity exige sa propre Activity (pas un Fragment)
|
||||||
|
- Un seul player Unity actif à la fois
|
||||||
|
- Lifecycle : pause/resume coordonné avec les autres composants
|
||||||
|
|
||||||
|
### 6.2 Specs rendu
|
||||||
|
|
||||||
|
| Paramètre | Valeur |
|
||||||
|
|-----------|--------|
|
||||||
|
| Mesh | 50-80K vertices, topology quad subdivisée |
|
||||||
|
| Texture diffuse | 4096×4096 |
|
||||||
|
| Normal map | 2048×2048 (détail pores) |
|
||||||
|
| Roughness map | 1024×1024 |
|
||||||
|
| Blendshapes | 52 (ARKit-compatible) |
|
||||||
|
| Shading | PBR + subsurface scattering approx. (skin shader) |
|
||||||
|
| Target framerate | 60fps (stabilité thermique pour sessions longues de 15-30 min) |
|
||||||
|
| Résolution rendu | Natif 2400×3392 ou 80% avec upscale |
|
||||||
|
| Antialiasing | MSAA 4x ou TAA |
|
||||||
|
| Éclairage | 1 directionnelle + 1 ambient + IBL (image-based lighting) |
|
||||||
|
|
||||||
|
Budget GPU estimé : <15% de l'Adreno 830 pour un seul personnage.
|
||||||
|
|
||||||
|
### 6.3 Style visuel
|
||||||
|
|
||||||
|
**Approche photoréaliste en premier**, fallback semi-stylisé si qualité insuffisante :
|
||||||
|
|
||||||
|
Pour le photoréalisme :
|
||||||
|
- Skin shader avec subsurface scattering (pre-integrated SSS ou screen-space SSS)
|
||||||
|
- Normal map pore-level
|
||||||
|
- Specular lobe dual (peau grasse vs sèche)
|
||||||
|
- Eye shader avec refraction cornée
|
||||||
|
- Anti-aliasing agressif (les bords du visage à 3392px montrent tout)
|
||||||
|
|
||||||
|
Si le résultat tombe dans l'uncanny valley :
|
||||||
|
- Passer en semi-stylisé (peau lissée, yeux légèrement agrandis, shader toon subtil)
|
||||||
|
- Réduit les exigences de texture et de normal map
|
||||||
|
- Plus chaleureux pour du support émotionnel
|
||||||

## 7. Lip sync
|
||||||
|
|
||||||
|
### 7.1 Pipeline
|
||||||
|
|
||||||
|
```
|
||||||
|
TTS Qwen3-TTS → Audio PCM 24kHz
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
OVRLipSync (Meta, Android NDK)
|
||||||
|
ou uLipSync (Unity, plus léger)
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
15 visèmes Oculus → mapping vers 52 blendshapes ARKit
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
Interpolation cubique Hermite (pas linéaire)
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
Coarticulation (lookahead 2-3 frames)
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
Blendshape weights à 60fps → SkinnedMeshRenderer Unity
|
||||||
|
```
|
||||||
|
|
||||||
|
### 7.2 Qualité lip sync sur grand écran
|
||||||
|
|
||||||
|
Les lèvres font ~300px de large à plein écran. Exigences :
|
||||||
|
|
||||||
|
- **52 blendshapes ARKit** (pas seulement 15 visèmes) — lèvres supérieure/inférieure/gauche/droite indépendantes
|
||||||
|
- **60fps** de mise à jour des poids (pas 30 — les transitions sont visibles sur 144Hz)
|
||||||
|
- **Interpolation cubique Hermite** entre keyframes — le linéaire donne un effet robotique
|
||||||
|
- **Coarticulation** : le shape de la bouche pour "ba" dépend de la voyelle suivante. 2-3 frames de lookahead dans le buffer audio
|
||||||
|
|
||||||
|
### 7.3 Mapping visèmes → blendshapes
|
||||||
|
|
||||||
|
Les 15 visèmes OVR se décomposent en mouvements de blendshapes multiples :
|
||||||
|
|
||||||
|
| Visème OVR | Blendshapes ARKit activés |
|
||||||
|
|-----------|--------------------------|
|
||||||
|
| PP (p/b/m) | mouthClose + mouthPucker |
|
||||||
|
| FF (f/v) | mouthFunnel + jawOpen(0.1) |
|
||||||
|
| TH (th) | tongueOut + jawOpen(0.2) |
|
||||||
|
| AA (a) | jawOpen(0.6) + mouthWideLeft/Right |
|
||||||
|
| OO (ou) | mouthPucker + mouthFunnel + jawOpen(0.3) |
|
||||||
|
| EE (i/e) | mouthSmileLeft/Right + jawOpen(0.2) |
|
||||||
|
| ... | ... |
|
||||||
|
|
||||||
|
Chaque visème active 2-5 blendshapes avec des poids différents → résultat plus riche que 15 shapes binaires.
|
||||||
|
|

|
||||||
|
|
||||||
|
## 8. Expressions émotionnelles
|
||||||
|
|
||||||
|
### 8.1 Émotions depuis le LLM
|
||||||
|
|
||||||
|
Le LLM Qwen3-0.6B tagger ses réponses avec des émotions **inline**, y compris au milieu des phrases :
|
||||||
|
|
||||||
|
```
|
||||||
|
Prompt système :
|
||||||
|
"Insère des tags d'émotion [joie], [tristesse], [empathie], [encouragement],
|
||||||
|
[neutre], [surprise] dans ta réponse quand l'émotion change."
|
||||||
|
|
||||||
|
Réponse LLM :
|
||||||
|
"[empathie] Je comprends que cette situation soit difficile.
|
||||||
|
[encouragement] Mais tu as déjà fait un grand pas en en parlant.
|
||||||
|
[joie] C'est vraiment courageux de ta part."
|
||||||
|
```
|
||||||
|
|
||||||
|
L'app parse les tags au fil du texte. Chaque tag déclenche une transition d'expression sur l'avatar **synchronisée avec le TTS** — l'émotion change au moment où la phrase correspondante est prononcée, pas avant.
|
||||||
|
|
||||||
|
### 8.2 Mapping émotion → expressions faciales
|
||||||
|
|
||||||
|
| Émotion LLM | Blendshapes dominants | Intensité |
|
||||||
|
|-------------|----------------------|-----------|
|
||||||
|
| joie | mouthSmile + cheekSquint + eyeSquint | 0.6-0.8 |
|
||||||
|
| tristesse | browInnerUp + mouthFrown + eyeWide(0.1) | 0.4-0.6 |
|
||||||
|
| empathie | browInnerUp(0.3) + mouthSmile(0.2) + headTilt | 0.3-0.5 |
|
||||||
|
| encouragement | browUp + mouthSmile(0.5) + nod | 0.5-0.7 |
|
||||||
|
| surprise | eyeWide + browUp + jawOpen(0.3) | 0.5-0.7 |
|
||||||
|
| neutre | repos + micro-expressions | 0.0-0.1 |
|
||||||
|
|
||||||
|
Les expressions se **blendent avec le lip sync** — l'avatar peut sourire tout en parlant.
|
||||||
|
|
||||||
|
### 8.3 Transitions
|
||||||
|
|
||||||
|
- Transition entre émotions : **ease-in-out sur 500ms** (pas de snap brutal)
|
||||||
|
- L'émotion s'applique sur la durée de la phrase TTS
|
||||||
|
- Les micro-expressions (léger sourire, haussement de sourcils) ajoutent du naturel
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 9. Idle animations — L'avatar vivant
|
||||||
|
|
||||||
|
Un avatar figé quand il ne parle pas = immédiatement "mort". Animations subtiles obligatoires :
|
||||||
|
|
||||||
|
| Animation | Fréquence | Amplitude |
|
||||||
|
|-----------|-----------|-----------|
|
||||||
|
| Clignement des yeux | Aléatoire, ~15-20/min | Naturel (rapide : 150ms) |
|
||||||
|
| Micro-saccades oculaires | Continu, 2-3/s | ±2° aléatoire |
|
||||||
|
| Respiration | Continue, ~16/min | Léger mouvement épaules/poitrine |
|
||||||
|
| Micro-expressions | Aléatoire, toutes les 3-8s | Très subtil (0.02-0.05) |
|
||||||
|
| Mouvement tête | Lent, continu | ±2° drift aléatoire |
|
||||||
|
|
||||||
|
Ces animations sont procédurales (pas des clips) — elles se blendent naturellement avec le lip sync et les émotions.
|
||||||

### Pipeline simplifié
|
||||||
|
|
||||||
|
```
|
||||||
|
Asset pré-fait (ours en peluche .glb)
|
||||||
|
├── Mesh : 10-20K vertices
|
||||||
|
├── 15-20 blendshapes (visèmes + sourire + triste + surprise)
|
||||||
|
├── Texture : stylisée, pré-faite
|
||||||
|
└── Rig : squelette simple (tête + corps)
|
||||||
|
│
|
||||||
|
Même pipeline lip sync + émotions
|
||||||
|
│
|
||||||
|
Pas de capture nécessaire
|
||||||
|
```
|
||||||
|
|
||||||
|
- Pas de reconstruction faciale
|
||||||
|
- Pas de voice cloning (voix synthétique par défaut ou voix pré-enregistrée)
|
||||||
|
- L'ours en peluche fait les mêmes expressions et lip sync que l'avatar humain
|
||||||
|
- **Premier livrable** pour valider le pipeline complet avant le mode adulte

## 11. Multi-utilisateurs et profils
|
||||||
|
|
||||||
|
### Modèle de profils
|
||||||
|
|
||||||
|
Un **profil** = un avatar (visage + voix). Un **utilisateur** = une personne qui utilise Kazeia.
|
||||||
|
|
||||||
|
```
|
||||||
|
Profil "Dr. Martin"
|
||||||
|
├── Avatar 3D (mesh, texture, blendshapes)
|
||||||
|
├── X-vector voix
|
||||||
|
├── Vidéo consentement
|
||||||
|
└── Permissions :
|
||||||
|
├── Utilisateur: Léa (autorisé)
|
||||||
|
├── Utilisateur: Hugo (autorisé)
|
||||||
|
└── Mode: multi-utilisateur (autorisé par Dr. Martin)
|
||||||
|
|
||||||
|
Profil "Maman de Léa"
|
||||||
|
├── Avatar 3D + voix
|
||||||
|
└── Permissions :
|
||||||
|
└── Utilisateur: Léa uniquement (mono-utilisateur)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Règles
|
||||||
|
|
||||||
|
- **Création** : la personne filmée crée le profil et donne son consentement
|
||||||
|
- **Mono-utilisateur** (par défaut) : le profil n'est utilisable que par un seul utilisateur désigné
|
||||||
|
- **Multi-utilisateur** : la personne doit explicitement autoriser le partage lors du consentement
|
||||||
|
- Phrase modifiée : *"...pour un usage partagé avec les utilisateurs que j'autorise"*
|
||||||
|
- **Révocation** : la personne peut révoquer son profil à tout moment (suppression avatar + voix, vidéo consentement conservée)
|
||||||
|
- **Pas de transfert** : un profil ne peut pas être copié vers un autre appareil (lié au device)
|
||||||
|
|
||||||
|
### Stockage profils
|
||||||
|
|
||||||
|
```
|
||||||
|
/data/data/com.kazeia/profiles/
|
||||||
|
├── profile_001/
|
||||||
|
│ ├── consent_video.enc (chiffré, non supprimable)

|
||||||
|
|
||||||
|
## 12. Mode dégradé
|
||||||
|
|
||||||
|
Si la personne ne souhaite pas un avatar photoréaliste de son visage :
|
||||||
|
|
||||||
|
| Option | Description | Voix |
|
||||||
|
|--------|------------|------|
|
||||||
|
| **Semi-stylisé** | Son visage mais en style 3D animation (Pixar-like) | Sa voix clonée |
|
||||||
|
| **Avatar générique** | Visage prédéfini parmi un catalogue | Sa voix clonée |
|
||||||
|
| **Personnage** | Ours en peluche ou autre mascotte | Sa voix clonée |
|
||||||
|
| **Voix seule** | Pas d'avatar, écran avec animation abstraite | Sa voix clonée |
|
||||||
|
|
||||||
|
Le choix est fait lors de la création du profil. Le voice cloning reste disponible dans tous les modes (seul le visuel change).
|
||||||
|
|
||||||
|
Le style semi-stylisé utilise le même pipeline de capture mais applique un **style transfer** au rendu :
|
||||||
|
- Peau lissée (pas de pores)
|
||||||
|
- Yeux légèrement agrandis
|
||||||
|
- Proportions adoucies
|
||||||
|
- Shader toon subtil au lieu de PBR réaliste
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 13. Mise à jour du profil
|
||||||
|
|
||||||
|
L'utilisateur ou la personne du profil peut mettre à jour les photos :
|
||||||
|
|
||||||
|
- **Ajout de photos** : nouvelles vues → amélioration texture + géométrie
|
||||||
|
- **Changement d'apparence** : lunettes, coupe de cheveux → re-capture partielle
|
||||||
|
- **Vieillissement** : re-capture complète tous les X mois si souhaité
|
||||||
|
- **Process** : même protocole de capture (phase 1 + 3), pas besoin de re-filmer le consentement
|

## 14. Simultanéité TTS + Avatar
|
||||||
|
|
||||||
|
L'avatar et le TTS travaillent ensemble en temps réel :
|
||||||
|
|
||||||
|
```
|
||||||
|
Timeline d'une réponse Kazeia :
|
||||||
|
|
||||||
|
t=0s LLM génère texte + tag émotion
|
||||||
|
t=0.1s Avatar reçoit émotion → transition expression (500ms ease-in)
|
||||||
|
t=0.1s TTS démarre génération (Hexagon NPU)
|
||||||
|
t=6s Génération terminée → hexStopRunner()
|
||||||
|
t=6.5s QNN decode audio (3.5s)
|
||||||
|
t=10s Audio prêt → AudioTrack.play()
|
||||||
|
→ OVRLipSync analyse en temps réel
|
||||||
|
→ Blendshape weights envoyés à Unity à 60fps
|
||||||
|
→ Avatar parle avec lip sync + émotion
|
||||||
|
t=14s Audio terminé → avatar retour idle (ease-out 500ms)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Pas de streaming pour l'instant** (conflit DSP hexagon/QNN). L'avatar affiche l'émotion et les idle animations pendant la génération TTS, puis commence le lip sync quand l'audio est prêt.
|
||||||
|
|
||||||
|
Le lip sync est synchrone avec l'audio — Unity lit le même buffer PCM que AudioTrack.

### Stockage sur l'appareil
|
||||||
|
|
||||||
|
| Donnée | Taille | Chiffré | Supprimable | Durée |
|
||||||
|
|--------|--------|---------|-------------|-------|
|
||||||
|
| Vidéo consentement | ~30 MB | AES-256 | **Non** (preuve légale) | Permanent |
|
||||||
|
| Photos capture | ~50 MB | Non (temp) | **Supprimées** après traitement | ~2 min |
|
||||||
|
| Audio brut | ~1 MB | Non (temp) | **Supprimé** après extraction x-vector | ~1 min |
|
||||||
|
| X-vector voix | 4 KB | AES-256 | Oui (supprime avatar) | Tant que avatar existe |
|
||||||
|
| Mesh avatar | ~5 MB | AES-256 | Oui | Tant que avatar existe |
|
||||||
|
| Texture avatar | ~15 MB | AES-256 | Oui | Tant que avatar existe |
|
||||||
|
| Blendshapes | ~2 MB | AES-256 | Oui | Tant que avatar existe |
|
||||||
|
|
||||||
|
### Principes RGPD
|
||||||
|
|
||||||
|
- **Rien ne quitte l'appareil** — tout le traitement est on-device
|
||||||
|
- **Consentement explicite** — vidéo avec déclaration orale comme preuve
|
||||||
|
- **Droit à l'effacement** — l'utilisateur peut supprimer son avatar (sauf vidéo consentement)
|
||||||
|
- **Minimisation** — photos et audio brut supprimés dès que traités
|
||||||
|
- **Pas de biométrie stockée** — le x-vector seul ne permet pas de reconnaître une voix (vecteur de 1024 dimensions, non réversible)

### Communication KazeiaService ↔ Unity
|
||||||
|
|
||||||
|
- **Java → C#** : `UnityPlayer.UnitySendMessage("AvatarController", "OnEmotion", "joie")`
|
||||||
|
- **Audio → lip sync** : SharedMemory ou AudioTrack partagé — Unity lit le même buffer audio
|
||||||
|
- **C# → Java** : callback via `AndroidJavaObject` pour les événements Unity (avatar ready, etc.)

## 3. Résultats des benchmarks
|
||||||
|
|
||||||
|
### 3.1 Test CPU (NEON ARM64) - llama.cpp
|
||||||
|
|
||||||
|
**Framework** : llama.cpp compilé via NDK r27d, backend CPU NEON
|
||||||
|
**Compilation** : `GGML_CPU_AARCH64=ON`, `GGML_OPENMP=OFF`
|
||||||
|

#### Gemma 3 4B - Scaling par nombre de threads
|
||||||
|
|
||||||
|
| Threads | Prefill 512 tok (tok/s) | Decode 128 tok (tok/s) | Scaling |
|
||||||
|
|---:|---:|---:|---|
|
||||||
|
| 1 | 2.18 | 1.71 | baseline |
|
||||||
|
| 2 | 7.48 | 3.35 | ~2x |
|
||||||
|
| 4 | 14.92 | 6.55 | ~3.8x |
|

|
| 6 | 19.16 | 11.16 | ~6.5x |
|
||||||
|
| **8** | **23.22** | **16.00** | **~9.4x** |
|

| **Qwen3-0.6B** | 604 Mo | Q8_0 | **163.25** | **68.23** |
|
||||||
|
| Qwen3-4B | 2.32 Go | Q4_K_M | 19.92 | 15.51 |

|
| Gemma 3 4B | 2.20 Go | Q4_0 | 23.54 | 16.31 |
|
||||||
|
|
||||||
|
**Observations CPU** :
|
||||||
|
- Le scaling est quasi-linéaire jusqu'à 8 threads (excellent pour les coeurs Oryon)
|
||||||
|
- Q4_K_M et Q4_0 ont des performances quasi identiques (~1% de différence)
|
||||||
|
- Le petit modèle Qwen3-0.6B atteint **68 tok/s** grâce à sa taille réduite (tient dans le cache)
|
||||||
|
- **Thermal throttling sévère** : après usage intensif, la tablette chauffe à 55°C et les performances chutent à ~5-7 tok/s (÷3)
|
||||||

### 3.2 Test GPU Vulkan (Adreno 830) - ÉCHEC
|
||||||
|
|
||||||
|
**Modèle** : Gemma 3 4B (Q4_K_M et Q4_0)
|
||||||
|
**Framework** : llama.cpp compilé avec `GGML_VULKAN=ON`
|
||||||
|
**Headers Vulkan** : Khronos Vulkan-Headers v1.3.275 (aligné avec le NDK)
|
||||||
|
|
||||||
|
| Test | Modèle | Config | Résultat |
|
||||||
|
|---|---|---|---|
|
||||||
|
| Vulkan ngl=99 | Q4_K_M | Full GPU offload | **CRASH** : `Compute pipeline creation failed for mul_mat_vec_q4_k_f32_f32` |
|
||||||
|
| Vulkan ngl=99 | Q4_0 | Full GPU offload | **CRASH** : `vk::Queue::submit: ErrorDeviceLost` |
|
||||||
|
| Vulkan ngl=1 | Q4_0 | 1 layer GPU | **0.65 tok/s** (25x plus lent que CPU) |
|
||||||
|
|
||||||
|
**Verdict** : Le GPU Vulkan Adreno 830 est **inutilisable** pour l'inférence LLM via llama.cpp. Les compute shaders ne sont pas compatibles avec le driver Vulkan Qualcomm.
|
||||||

### 3.3 Test NPU (Hexagon HTP v79) - Genie SDK
|
||||||
|
|
||||||
|
**Framework** : Qualcomm Genie SDK
|
||||||
|
**Backend** : QnnHtp avec context binaries pré-compilés (Qualcomm AI Hub)
|
||||||
|
|
||||||
|
#### Qwen3-4B (modèle pré-compilé Qualcomm AI Hub)
|
||||||
|
|
||||||
|
| Métrique | Valeur |
|
||||||
|
|---|---|
|
||||||
|
| SDK | QNN 2.42.0 |
|
||||||
|
| Format | 4 context binaries w4a16 (total ~3 Go) |
|
||||||
|
| Tokens générés | 4096 (contexte max) |
|
||||||
|
| Temps total | ~207 secondes |
|
||||||
|
| **Débit decode** | **~19.8 tok/s** |
|
||||||
|
| RAM allouée | 344 Mo (8 shared buffers) |
|
||||||
|
|
||||||
|
#### Qwen3-0.6B (conversion manuelle via transformer-composer)
|
||||||
|
|
||||||
|
| Tentative | Backend | Résultat |
|
||||||
|
|---|---|---|
|
||||||
|
| `QnnGenAiTransformer` | CPU (via Genie) | **CRASH** : dimensions de tenseurs incompatibles (GQA non supporté) |
|
||||||
|
|
||||||
|
Le backend `QnnGenAiTransformer` du SDK 2.37 ne gère pas correctement l'architecture GQA (Grouped Query Attention) de Qwen3. Seuls les modèles **pré-compilés Qualcomm AI Hub** avec le backend `QnnHtp` fonctionnent de manière fiable.

### 3.4 Test NPU (Hexagon HTP v79) - ExecuTorch + QNN
|
||||||
|
|
||||||
|
**Framework** : ExecuTorch (Meta) + QNN delegate (Qualcomm)
|
||||||
|
**SDK** : QNN 2.42.0
|
||||||
|
**Modèles** : Qwen3-0.6B, Qwen3-1.7B et Mistral-Nemo 12B exportés au format `.pte` avec quantification INT4

|
||||||
|
> Bonjour, je suis désolé de vous voir triste. C'est vraiment douloureux de voir des sentiments aussi difficiles. Mais je suis ici pour vous soutenir.
|
||||||
|
> - Passez un peu de temps à l'air : l'oxygène et le soleil peuvent aider à détendre l'esprit.
|
||||||
|
> - Parlez à quelqu'un : partager vos émotions avec une amie, un proche ou même un thérapeute peut être très bénéfique.
|
||||||
|
> - Faites quelque chose de votre passion : une activité physique, une lecture peut vous aider à vous distraire.
|
||||||
|
> - Respirez : une respiration profonde peut aider à calmer l'esprit.

Ce modèle est le **meilleur candidat pour Kazeia** : réponses empathiques de qualité en français, vitesse excellente (25.7 tok/s), et taille raisonnable (1.7 Go).
|
||||||
|
|
||||||
|
#### Résultats ExecuTorch Mistral-Nemo 12B (modèle utilisé par kazeia.py)
|
||||||
|
|
||||||
|
Export réussi grâce à :
|
||||||
|
- Ajout d'un profil custom `mistral_nemo_12b` dans ExecuTorch (config + `convert_weights` + `QuantRecipe`)
|
||||||
|
- `num_sharding = 8` (40 couches ÷ 8 = 5 couches par shard)
|
||||||
|
- 192 Go de swap sur btrfs (`btrfs filesystem mkswapfile`)
|
||||||
|
|
||||||
|
| Métrique | Valeur |
|
||||||
|
|---|---|
|
||||||
|
| **Débit decode** | **5.1 tok/s** |
|
||||||
|
| **Débit prefill** | **156.9 tok/s** |
|
||||||
|
| Taille .pte | 7.4 Go |
|
||||||
|
| Tokens générés | 244 en 47.7 secondes |
|
||||||
|
| Réponse | Excellent français, empathique, conseil professionnel |
|
||||||
|
|
||||||
|
**Exemple de réponse Mistral-Nemo 12B sur le NPU** :
|
||||||
|
> Je suis désolé que vous vous sentiez triste. Il y a plusieurs choses que vous pouvez faire pour vous sentir mieux. Vous pouvez essayer de faire de l'exercice, de méditer, de parler à un ami ou à un membre de votre famille, de vous offrir une petite gâterie, ou de vous reposer. Vous pouvez également essayer de vous concentrer sur les choses positives de votre vie. Si votre tristesse est persistante, il peut être utile de parler à un professionnel de la santé mentale pour obtenir de l'aide supplémentaire.
|
||||||
|
|
||||||
|
**Observation clé** : le prefill est **21x plus rapide** que le CPU (156.9 vs 7.25 tok/s) grâce aux TOPS du NPU, mais le decode est **16% plus lent** (5.1 vs 6.05 tok/s) car le modèle de 7.4 Go sature la bande passante mémoire de la tablette.
|
||||||
|
|
||||||
|
#### RAM nécessaire pour l'export .pte
|
||||||
|
|
||||||
|
L'export `.pte` consomme beaucoup de mémoire. Le **sharding** réduit la mémoire de la phase de compilation QNN mais **pas de la quantification** (`prepare_pt2e`) qui charge le modèle entier.

| **Qwen3-0.6B** | 1 | ~20 Go | 660 Mo | ~20 min | **OK** (54 Go RAM) |
|
||||||
|
| **Qwen3-1.7B** | 1→4 | ~48 Go | 1.7 Go | ~25 min | **OK** (62 Go RAM) |
|
||||||
|
| **Mistral-Nemo 12B** | 8 | **~250 Go** | 7.4 Go | ~1h40 | **OK** (62 Go RAM + 192 Go swap) |
|
||||||
|
| Qwen3-4B (estimé) | 4 | ~130 Go | ~3-4 Go | ~1h | Nécessite 128+ Go |

## 4. Synthèse comparative
|
||||||
|
|
||||||
|
### 4.1 Comparaison à armes égales : Qwen3-0.6B (596M paramètres)
|
||||||
|
|
||||||
|
| Framework | Backend | Decode (tok/s) | Status |
|
||||||
|
|---|---|---:|---|
|
||||||
|
| **ExecuTorch + QNN** | **NPU Hexagon** | **69.3** | Fonctionnel |
|
||||||
|
| llama.cpp | CPU NEON (8 threads) | 68.2 | Fonctionnel |
|
||||||
|
| Genie SDK | GenAiTransformer | CRASH | GQA incompatible |
|
||||||
|
|
||||||
|
**Résultat** : NPU et CPU sont **quasi identiques** (~69 tok/s) sur ce petit modèle. La bande passante mémoire LPDDR5X (~77 Go/s) est le facteur limitant pour les deux.
|
||||||
|
|
||||||
|
### 4.2 Comparaison : Qwen3-1.7B (1.7B paramètres)
|
||||||
|
|
||||||
|
| Framework | Backend | Decode (tok/s) | Status |
|
||||||
|
|---|---|---:|---|
|
||||||
|
| **ExecuTorch + QNN** | **NPU Hexagon** | **25.7** | Fonctionnel |
|
||||||
|
| llama.cpp | CPU NEON (8 threads) | ~15.5 (estimé) | Fonctionnel |
|
||||||
|
|
||||||
|
**Résultat** : Le NPU est **~66% plus rapide** que le CPU. C'est le modèle avec le **meilleur rapport qualité/vitesse** pour Kazeia.
|
||||||
|
|
||||||
|
### 4.3 Comparaison : Qwen3-4B (4B paramètres)
|
||||||
|
|
||||||
|
| Framework | Backend | Decode (tok/s) | Status |
|
||||||
|
|---|---|---:|---|
|
||||||
|
| **Genie SDK (AI Hub)** | **NPU Hexagon** | **~19.8** | Fonctionnel |
|
||||||
|
| llama.cpp | CPU NEON (8 threads) | 15.5 | Fonctionnel |
|
||||||
|
| llama.cpp | GPU Vulkan | CRASH | Driver incompatible |
|
||||||
|
|
||||||
|
**Résultat** : Le NPU est **~27% plus rapide** que le CPU.
|
||||||
|
|
||||||
|
### 4.4 Comparaison : Mistral-Nemo 12B (12.25B paramètres - modèle de kazeia.py)
|
||||||
|
|
||||||
|
| Framework | Backend | Prefill (tok/s) | Decode (tok/s) | Status |
|
||||||
|
|---|---|---:|---:|---|
|
||||||
|
| **ExecuTorch + QNN** | **NPU Hexagon** | **156.9** | **5.1** | Fonctionnel |
|
||||||
|
| llama.cpp | CPU NEON (8 threads) | 7.25 | 6.05 | Fonctionnel |
|
||||||
|
|
||||||
|
**Résultat** : Le NPU est **21x plus rapide en prefill** mais **16% plus lent en decode**. Le modèle de 7.4 Go sature la bande passante mémoire LPDDR5X (~77 Go/s) en decode. Le NPU ne peut pas compenser par du calcul car chaque token nécessite de relire tous les poids.

|
||||||
|
|
||||||
|
| Modèle | Params | CPU decode (tok/s) | NPU decode (tok/s) | NPU prefill (tok/s) | NPU vs CPU (decode) | GPU Vulkan |

||||||
|
| Gemma 3 4B | 3.88B | 16.0 | Non testé | N/A | - | CRASH |
|
||||||
|
|
||||||
|
### 4.6 Conclusions clés
|
||||||
|
|
||||||
|
1. **Les petits modèles (< 1B)** : NPU ≈ CPU car tous deux limités par la bande passante mémoire (~77 Go/s)
|
||||||
|
2. **Les modèles moyens (1-2B)** : NPU gagne **+66%** en vitesse — c'est le **sweet spot**
|
||||||
|
3. **Les modèles plus gros (3-4B)** : NPU gagne **+27%** (Genie SDK, modèles pré-compilés)
|
||||||
|
4. **Les très gros modèles (12B+)** : NPU **perd en decode** (-16%) car la bande passante mémoire est saturée, mais **domine en prefill** (21x)
|
||||||
|
5. **Le GPU Vulkan Adreno 830** : inutilisable pour les LLM (driver crash)
|
||||||
|
5. **Thermal throttling** : le CPU chute à ÷3 après usage prolongé, le NPU est plus stable
|
||||||
|
6. **Qwen3-1.7B est le meilleur candidat pour Kazeia** : 25.7 tok/s sur NPU, excellent français, réponses empathiques structurées
|
||||||
|
7. **Mistral-Nemo 12B** (modèle actuel de kazeia.py) : fonctionne sur le NPU mais trop lent en decode (5.1 tok/s) — le modèle est surdimensionné pour la tablette
|
||||||
|
8. **Qualcomm annonce 29 tok/s** pour Qwen3-4B (notre test : ~20 tok/s → marge d'optimisation)
|
||||||

## 5. Analyse et recommandations
|
||||||
|
|
||||||
|
### 5.1 Choix du framework pour Kazeia
|
||||||
|
|
||||||
|
| Critère | llama.cpp (CPU) | Genie SDK (NPU) | ExecuTorch (NPU) |
|
||||||
|
|---|---|---|---|
|
||||||
|
| Facilité de déploiement | Excellente | Moyenne (modèles pré-compilés) | Complexe |
|
||||||
|
| Modèles supportés | Tous (GGUF) | Limité (AI Hub) | Limité (export RAM) |
|
||||||
|
| Performance decode (1-4B) | Bonne | Meilleure (+27%) | Meilleure (+66% pour 1.7B) |
|
||||||
|
| Efficacité batterie | Moyenne | Excellente | Excellente |
|
||||||
|
| Maintenance | Simple | SDK Qualcomm | SDK Meta + Qualcomm |
|
||||||
|
|
||||||
|
### 5.2 Recommandation stratégique
|
||||||
|
|
||||||
|
**Approche recommandée** :
|
||||||
|
- **Production principale** : ExecuTorch + QNN + **Qwen3-1.7B** sur NPU (25.7 tok/s, excellent français, 1.7 Go)
|
||||||
|
- **Alternative haute qualité** : Genie SDK + Qwen3-4B pré-compilé AI Hub (~19.8 tok/s, réponses plus riches)
|
||||||
|
- **Fallback universel** : llama.cpp CPU avec n'importe quel modèle GGUF (flexibilité maximale)
|
||||||
|
- **Non recommandé** : Mistral-Nemo 12B sur tablette (trop lent en decode : 5.1 tok/s NPU / 6 tok/s CPU)
|
||||||
|
- **R&D** : ExecuTorch + QNN pour les modèles custom (62 Go RAM + swap pour l'export)
|
||||||
|
|
||||||
|
### 5.3 Prochaines étapes
|
||||||
|
|
||||||
|
#### Court terme (immédiat)
|
||||||
|
- **Déployer Qwen3-1.7B** via ExecuTorch sur le NPU comme moteur principal de Kazeia (25.7 tok/s)
|
||||||
|
- Configurer les **stop tokens** Qwen3 (`<|im_end|>`) et le **system prompt** Kazeia
|
||||||
|
- Désactiver le **mode thinking** pour des réponses plus directes et rapides
|
||||||
|
- Construire le pipeline complet : prompt Kazeia → NPU → réponse
|
||||||
|
|
||||||
|
#### Moyen terme
|
||||||
|
- Construire une **application Android** intégrant le runtime ExecuTorch + QNN
|
||||||
|
- Implémenter le RAG localement (embeddings + base de connaissances)
|
||||||
|
- Tester le **Qwen3-4B via ExecuTorch** sur un serveur cloud (128+ Go RAM) pour comparer
|
||||||
|
- Optimiser la config Genie (perf_profile, cpu-mask) pour Qwen3-4B AI Hub
|
||||||
|
|
||||||
|
#### Long terme
|
||||||
|
- Fine-tuner un modèle français spécifique pour Kazeia, puis l'exporter via ExecuTorch
|
||||||
|
- Surveiller l'évolution du support Vulkan pour Adreno dans llama.cpp
|
||||||
|
- Suivre les nouveaux modèles sur Qualcomm AI Hub

### Gains mesurés
|

|
|
||||||
|
| Fonctionnalité | Sans Root | Avec Root | Gain |
|
||||||
|
|----------------|-----------|-----------|------|
|
||||||
|
| **LLM** | Indisponible | 93 tok/s (0.6B) / 46 tok/s (1.7B) | **∞** |
|
||||||
|
| **Prefill** | - | 451-1000 tok/s | **∞** |
|
||||||
|
| **TTFT** | - | 27-31ms | **∞** |
|
||||||
|
| **Pipeline complet** | Non (écho) | Oui (STT→LLM→TTS) | **Pipeline fonctionnel** |
|
||||||
|
| **GPU monitoring** | 0% | Fonctionne | Visibilité |
|
||||||
|
| **Whisper STT** | 1500ms (CPU) | 1500ms (CPU) | 0% (même backend) |
|
||||||
|
|
||||||
|
### Ce que le root débloque concrètement
|
||||||
|
|
||||||
|
1. **Accès au DSP/NPU via ExecuTorch** → LLM fonctionnel sur NPU
|
||||||
|
2. **libs QNN chargées correctement** → `libQnnModelDlc.so` + Skel dans ADSP_LIBRARY_PATH
|
||||||
|
3. **SELinux permissive** → pas de blocage d'accès
|
||||||
|
4. **Boot script** → permissions persistantes au redémarrage
|
||||||
|
5. **GPU sysfs** → monitoring temps réel
|
||||||
|
|
||||||
|
### Ce que le root ne change pas
|
||||||
|
|
||||||
|
1. Performances STT (whisper.cpp CPU identique)
|
||||||
|
2. TTS Android natif (identique)
|
||||||
|
3. Chatterbox TTS (OOM indépendant du root)

## Recommandations pour la Production
|
||||||
|
|
||||||
|
### Modèle LLM recommandé
|
||||||
|
|
||||||
|
**Qwen3-1.7B** — meilleur compromis qualité/vitesse :
|
||||||
|
- 46 tok/s suffisant pour conversation temps réel
|
||||||
|
- Qualité FR bonne pour l'écoute émotionnelle
|
||||||
|
- 1.7 GB RAM acceptable sur 16 GB device
|
||||||
|
- TTFT 27ms = réponse quasi instantanée
|
||||||
|
|
||||||
|
### Prochaines optimisations
|
||||||
|
|
||||||
|
1. **Whisper sur NPU** : le `qnn_whisper_runner` est compilé, réduirait STT de 1500ms à ~50ms
|
||||||
|
2. **Chatterbox quantifié** : réduire les modèles TTS pour éviter OOM
|
||||||
|
3. **Streaming LLM** : afficher les tokens au fur et à mesure de la génération
|
||||||
|
4. **ExecuTorch JNI natif** : intégrer directement en C++ au lieu du subprocess `su`
|
||||||

||||||
|
## Erreurs courantes
|
||||||
|
|
||||||
|
### `loadRemoteSymbols failed with err 4000`
|
||||||
|
- **Cause** : Libs Skel manquantes ou incompatibles
|
||||||
|
- **Fix** : Vérifier que `libQnnHtpV79Skel.so` vient du SDK 2.42 (hexagon-v79/unsigned/), pas du vendor
|
||||||
|
|
||||||
|
### `SoC model (SnapdragonModel) is unknown`
|
||||||
|
- **Cause** : Utilisation des libs vendor au lieu des libs SDK
|
||||||
|
- **Fix** : Ne PAS utiliser `/vendor/lib64/hw/audio/libQnn*.so`
|
||||||
|
|
||||||
|
### Runner se termine sans générer de texte
|
||||||
|
- **Cause** : `--shared_buffer` et `--output_path` manquants
|
||||||
|
- **Fix** : Ajouter les deux paramètres
|
||||||
|
|
||||||
|
### `Failed to create transport for device`
|
||||||
|
- **Cause** : `libQnnModelDlc.so` manquant
|
||||||
|
- **Fix** : Copier depuis `qnn_sdk_242/.../lib/aarch64-android/`

|
||||||
|
+---------------------------+-------------------+-------------------+
|
||||||
|
| Throughput (tokens/s) | 30-50 | 100-200 |
|
||||||
|
| Latence 1ere reponse | 1000-2000 ms | 200-500 ms |
|
||||||
|
| Memoire GPU | 4-6 GB | 3-4 GB |
|
||||||
|
| Utilisateurs simultanes | 1-2 | 5-10+ |
|
||||||
|
+---------------------------+-------------------+-------------------+
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
from vllm import LLM, SamplingParams
|
||||||
|
|
||||||
|
vllm_model = LLM(
|
||||||
|
model="./model/kazeia",
|
||||||
|
trust_remote_code=True,
|
||||||
|
dtype="float16",

|
top_p=0.8,
|
||||||
|
max_tokens=300,
|
||||||
|
repetition_penalty=1.2
|
||||||
|
)

# Guide Root - OnePlus Pad 3 (OPD2415) pour le projet Kazeia
|
||||||
|
|
||||||
|
## Pourquoi rooter ?
|
||||||
|
|
||||||
|
Le Snapdragon 8 Elite embarque un NPU (Neural Processing Unit) capable d'exécuter les modèles d'IA 10 à 100x plus vite que le CPU. Sans root, Android bloque l'accès aux librairies vendor Qualcomm (libcdsprpc.so, libQnnHtp.so) nécessaires pour communiquer avec le NPU depuis une application tierce.
|
||||||
|
|
||||||
|
### Impact sur les performances
|
||||||
|
|
||||||
|
| Composant | Sans root (CPU) | Avec root (NPU) | Gain |
|
||||||
|
|-----------|-----------------|------------------|------|
|
||||||
|
| **STT Whisper-Base** | ~1500ms | ~50ms | x30 |
|
||||||
|
| **LLM Qwen3-4B (Genie SDK)** | Indisponible (erreur -5) | ~30 tok/s | ∞ |
|
||||||
|
| **TTS Chatterbox** | OOM crash (1.4 GB RAM) | ~1-3s sur NPU | Fonctionne |
|
||||||
|
| **Monitoring GPU/NPU** | 0% (sysfs inaccessible) | Métriques temps réel | Visibilité |
|
||||||
|
| **Pipeline complet (STT→LLM→TTS)** | Impossible | ~4-8s end-to-end | Pipeline complet |
|
||||||
|
|
||||||
|
### Composants bloqués sans root
|
||||||
|
|
||||||
|
- **Genie SDK** : le `GenieDialogConfig_createFromJson()` retourne le code d'erreur -7 car il ne peut pas ouvrir les devices DSP
|
||||||
|
- **QNN HTP** : `libcdsprpc.so` nécessite `libhidlbase.so` du namespace vendor, inaccessible aux apps normales
|
||||||
|
- **ONNX Runtime QNN EP** : le QNN Execution Provider s'initialise mais ne peut pas communiquer avec le HTP
|
||||||
|
- **Sysfs monitoring** : `/sys/class/kgsl/` (GPU) et `/sys/class/devfreq/` (NPU) sont protégés par SELinux
|
||||||
|
|
||||||
|
### Ce qui fonctionne sans root
|
||||||
|
|
||||||
|
- Whisper.cpp sur CPU (STT)
|
||||||
|
- Android TTS natif (Google)
|
||||||
|
- ONNX Runtime sur CPU
|
||||||
|
- Silero VAD (ONNX CPU)
|
||||||
|
- LiteRT avec NNAPI (délégation partielle, limitée)
|
||||||
|
|

|
## Prérequis
|
||||||
|
|
||||||
|
- **Tablette** : OnePlus Pad 3 (OPD2415)
|
||||||
|
- **Firmware** : OPD2415_16.0.3.500(EX01) — OxygenOS 16 / Android 16 (API 36)
|
||||||
|
- **SoC** : Snapdragon 8 Elite (SM8750, plateforme "sun")
|
||||||
|
- **Slot actif** : A
|
||||||
|
- **Bootloader** : verrouillé (à déverrouiller)
|
||||||
|
- **PC** : avec ADB et Fastboot installés
|
||||||
|
- **Sauvegarde** : aucune donnée critique sur la tablette (le déverrouillage efface tout)
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Étape 1 — Activer le déverrouillage OEM
|
||||||
|
|
||||||
|
Sur la tablette :
|
||||||
|
|
||||||
|
1. **Paramètres → À propos de la tablette**
|
||||||
|
2. Taper **7 fois** sur "Numéro de build" pour activer les Options développeur
|
||||||
|
3. **Paramètres → Système → Options développeur**
|
||||||
|
4. Activer **Déverrouillage OEM**
|
||||||
|
5. Vérifier que **Débogage USB** est activé
|
||||||
|
|
||||||
|
Vérification depuis le PC :
|
||||||
|
|
||||||
|
```bash
|
||||||
|
adb shell getprop sys.oem_unlock_allowed
|
||||||
|
# Doit retourner "1"
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Étape 2 — Déverrouiller le bootloader
|
||||||
|
|
||||||
|
⚠️ **ATTENTION : Cette étape efface TOUTES les données de la tablette.**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Redémarrer en mode fastboot
|
||||||
|
adb reboot bootloader
|
||||||
|
|
||||||
|
# Attendre que la tablette soit en mode fastboot (écran avec logo)
|
||||||
|
# Vérifier la connexion
|
||||||
|
fastboot devices
|
||||||
|
|
||||||
|
# Déverrouiller le bootloader
|
||||||
|
fastboot flashing unlock
|
||||||
|
```
|
||||||
|
|
||||||
|
Sur la tablette :
|
||||||
|
- Utiliser les **boutons volume** pour sélectionner "Unlock the bootloader"
|
||||||
|
- Confirmer avec le **bouton power**
|
||||||
|
- La tablette va se réinitialiser et redémarrer
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Vérification
|
||||||
|
adb shell getprop ro.boot.vbmeta.device_state
|
||||||
|
# Doit retourner "unlocked"
|
||||||
|
```
|
||||||
|
|
||||||
|
Après le redémarrage :
|
||||||
|
- Reconfigurer la tablette (setup minimal)
|
||||||
|
- Réactiver les Options développeur + Débogage USB
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Étape 3 — Récupérer le firmware stock
|
||||||
|
|
||||||
|
Il faut le fichier `init_boot.img` de la **même version** de firmware installée.
|
||||||
|
|
||||||
|
### Option A : Extraire depuis un OTA complet
|
||||||
|
|
||||||
|
1. Télécharger le firmware OPD2415_16.0.3.500 depuis :
|
||||||
|
- [OnePlus Firmware Archive](https://www.oneplus.com/support/softwareupgrade)
|
||||||
|
- Ou communautés XDA/OnePlus
|
||||||
|
2. Extraire le ZIP
|
||||||
|
3. Trouver `init_boot.img` dans le payload :
|
||||||
|
```bash
|
||||||
|
# Si le firmware est un payload.bin
|
||||||
|
python3 payload_dumper.py payload.bin --out extracted/
|
||||||
|
# init_boot.img sera dans extracted/
|
||||||
|
```
|
||||||
|
|
||||||
|
### Option B : Extraire depuis la partition active
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Identifier la partition init_boot
|
||||||
|
adb shell ls -la /dev/block/by-name/init_boot*
|
||||||
|
|
||||||
|
# Extraire (nécessite un accès shell suffisant)
|
||||||
|
adb shell dd if=/dev/block/by-name/init_boot_a of=/data/local/tmp/init_boot.img
|
||||||
|
adb pull /data/local/tmp/init_boot.img
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Étape 4 — Patcher avec Magisk
|
||||||
|
|
||||||
|
1. **Télécharger Magisk** : [github.com/topjohnwu/Magisk/releases](https://github.com/topjohnwu/Magisk/releases)
|
||||||
|
- Prendre le fichier `Magisk-v28.x.apk` (dernière version stable)
|
||||||
|
|
||||||
|
2. **Installer Magisk sur la tablette** :
|
||||||
|
```bash
|
||||||
|
adb install Magisk-v28.x.apk
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Transférer init_boot.img sur la tablette** :
|
||||||
|
```bash
|
||||||
|
adb push init_boot.img /data/local/tmp/
|
||||||
|
```
|
||||||
|
|
||||||
|
4. **Patcher avec Magisk** :
|
||||||
|
- Ouvrir l'app Magisk sur la tablette
|
||||||
|
- Appuyer sur **"Installer"** à côté de "Magisk"
|
||||||
|
- Choisir **"Sélectionner et patcher un fichier"**
|
||||||
|
- Naviguer vers `/data/local/tmp/init_boot.img`
|
||||||
|
- Attendre la fin du patching
|
||||||
|
- Le fichier patché sera dans `/storage/emulated/0/Download/magisk_patched-xxxxx.img`
|
||||||
|
|
||||||
|
5. **Récupérer l'image patchée** :
|
||||||
|
```bash
|
||||||
|
adb pull /storage/emulated/0/Download/magisk_patched-28100_xxxxx.img
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Étape 5 — Flasher l'image patchée
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Redémarrer en fastboot
|
||||||
|
adb reboot bootloader
|
||||||
|
|
||||||
|
# Flasher l'image patchée sur la partition init_boot
|
||||||
|
fastboot flash init_boot magisk_patched-28100_xxxxx.img
|
||||||
|
|
||||||
|
# Redémarrer
|
||||||
|
fastboot reboot
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Étape 6 — Vérification
|
||||||
|
|
||||||
|
Après le redémarrage :
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Vérifier que Magisk est actif
|
||||||
|
adb shell su -c id
|
||||||
|
# Doit retourner: uid=0(root) gid=0(root)
|
||||||
|
|
||||||
|
# Vérifier l'accès aux libs vendor
|
||||||
|
adb shell su -c "ls /vendor/lib64/libcdsprpc.so"
|
||||||
|
adb shell su -c "ls /vendor/lib64/libQnnHtp.so"
|
||||||
|
|
||||||
|
# Vérifier l'accès au DSP
|
||||||
|
adb shell su -c "ls /dev/adsprpc-smd"
|
||||||
|
|
||||||
|
# Vérifier les sysfs GPU
|
||||||
|
adb shell su -c "cat /sys/class/kgsl/kgsl-3d0/gpubusy"
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Étape 7 — Configuration post-root pour Kazeia
|
||||||
|
|
||||||
|
### Permissions DSP pour l'app
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Donner accès au DSP à l'app Kazeia
|
||||||
|
adb shell su -c "chmod 666 /dev/adsprpc-smd"
|
||||||
|
adb shell su -c "chmod 666 /dev/cdsprpc-smd"
|
||||||
|
|
||||||
|
# Ou via Magisk module pour persister après reboot
|
||||||
|
```
|
||||||
|
|
||||||
|
### Module Magisk recommandé
|
||||||
|
|
||||||
|
Créer un module Magisk qui :
|
||||||
|
- Rend les libs QNN accessibles aux apps
|
||||||
|
- Ouvre les permissions DSP au boot
|
||||||
|
- Expose les sysfs GPU/NPU
|
||||||
|
|
||||||
|
### Variables d'environnement
|
||||||
|
|
||||||
|
L'app devra setter ces variables avant de charger les libs QNN :
|
||||||
|
```
|
||||||
|
ADSP_LIBRARY_PATH=/vendor/lib64/
|
||||||
|
LD_LIBRARY_PATH=/vendor/lib64/
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Risques et précautions
|
||||||
|
|
||||||
|
### Ce que le root implique
|
||||||
|
|
||||||
|
- **Garantie** : techniquement annulée (mais reversible en re-verrouillant le bootloader)
|
||||||
|
- **Mises à jour OTA** : ne fonctionneront plus automatiquement (flash manuel nécessaire)
|
||||||
|
- **SafetyNet / Play Integrity** : certaines apps (banque, Netflix) peuvent refuser de fonctionner
|
||||||
|
- Solution : module Magisk "Universal SafetyNet Fix" ou "Play Integrity Fix"
|
||||||
|
- **Sécurité** : le root expose le système — ne pas installer d'apps douteuses
|
||||||
|
|
||||||
|
### Comment revenir en arrière
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Re-verrouiller le bootloader (efface tout)
|
||||||
|
adb reboot bootloader
|
||||||
|
fastboot flashing lock
|
||||||
|
# Confirmer sur la tablette
|
||||||
|
fastboot reboot
|
||||||
|
```
|
||||||
|
|
||||||
|
### Sauvegarde avant root
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Sauvegarder les modèles déjà poussés
|
||||||
|
adb pull /data/local/tmp/kazeia/ ./backup_kazeia/
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Résumé des commandes
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# 1. Déverrouiller
|
||||||
|
adb reboot bootloader
|
||||||
|
fastboot flashing unlock
|
||||||
|
# Confirmer sur tablette
|
||||||
|
|
||||||
|
# 2. Après reconfiguration tablette
|
||||||
|
adb install Magisk-v28.x.apk
|
||||||
|
adb push init_boot.img /data/local/tmp/
|
||||||
|
|
||||||
|
# 3. Patcher sur tablette via app Magisk, puis récupérer
|
||||||
|
adb pull /storage/emulated/0/Download/magisk_patched-*.img
|
||||||
|
|
||||||
|
# 4. Flasher
|
||||||
|
adb reboot bootloader
|
||||||
|
fastboot flash init_boot magisk_patched-*.img
|
||||||
|
fastboot reboot
|
||||||
|
|
||||||
|
# 5. Vérifier
|
||||||
|
adb shell su -c id
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Après le root — Impact sur Kazeia
|
||||||
|
|
||||||
|
Une fois rooté, modifier `KazeiaApplication.kt` pour ajouter les chemins vendor :
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
companion object {
|
||||||
|
const val MODELS_DIR = "/data/local/tmp/kazeia/models"
|
||||||
|
|
||||||
|
init {
|
||||||
|
// Avec root, les libs vendor sont accessibles
|
||||||
|
System.setProperty("ADSP_LIBRARY_PATH", "/vendor/lib64/")
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Les composants suivants deviendront fonctionnels :
|
||||||
|
- ✅ Genie SDK → LLM Qwen3-4B sur NPU
|
||||||
|
- ✅ ONNX Runtime QNN EP → Whisper encoder/decoder sur NPU
|
||||||
|
- ✅ Monitoring GPU/NPU via sysfs
|
||||||
|
- ✅ Chatterbox TTS sur NPU (réduction mémoire)
|
||||||
|

# Rapport TTS - Qwen3-TTS sur OnePlus Pad 3
|
||||||
|
|
||||||
|
**Date** : 26 mars 2026
|
||||||
|
**Objectif** : Synthèse vocale avec clonage de voix en français pour le chatbot Kazeia
|
||||||
|
**Tablette** : OnePlus Pad 3 (Snapdragon 8 Elite, NPU Hexagon HTP v79)
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 1. Modèles TTS évalués
|
||||||
|
|
||||||
|
### 1.1 Chatterbox Multilingual (ONNX)
|
||||||
|
|
||||||
|
| Caractéristique | Détail |
|
||||||
|
|---|---|
|
||||||
|
| Repo | `onnx-community/chatterbox-multilingual-ONNX` |
|
||||||
|
| Architecture | LLM 0.5B (Llama) + speech encoder + conditional decoder |
|
||||||
|
| Français | Oui (23 langues) |
|
||||||
|
| Clonage vocal | Oui |
|
||||||
|
| Format | ONNX (FP32, FP16, Q4F16) |
|
||||||
|
| Taille totale | ~1.5 Go (Q4F16) |
|
||||||
|
|
||||||
|
**Résultat** : Le modèle charge et génère des tokens mais le **décodage audio ne fonctionne que sur la première seconde**. Les versions quantifiées (FP16, Q4F16) ne produisent pas le stop token, résultant en du silence après le début. Seul le FP32 (2 Go LM) fonctionne correctement mais uniquement pour des phrases très courtes.
|
||||||
|
|
||||||
|
**Verdict** : Non fiable pour la production.
|
||||||
|
|
||||||
|
### 1.2 Qwen3-TTS (PyTorch natif)
|
||||||
|
|
||||||
|
| Caractéristique | 0.6B Base | 1.7B CustomVoice | 1.7B Base |
|
||||||
|
|---|---|---|---|
|
||||||
|
| Clonage vocal | Oui (x_vector) | Non (voix intégrées) | Oui (x_vector) |
|
||||||
|
| Français | Oui | Oui | Oui |
|
||||||
|
| Taille FP32 | ~1.8 Go | ~4.5 Go | ~4.5 Go |
|
||||||
|
| Qualité clonage | Bonne | N/A | Bonne |
|
||||||
|
|
||||||
|
**Résultat** : Fonctionne parfaitement sur CPU avec les voix françaises du projet Kazeia.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. Tests Qwen3-TTS sur CPU (PC)
|
||||||
|
|
||||||
|
**Phrase** : *"Bonjour, je comprends que vous soyez triste. Je suis là pour vous écouter."*
|
||||||
|
|
||||||
|
### 2.1 Résultats par modèle et voix
|
||||||
|
|
||||||
|
| Modèle | Voix | Audio | Temps | Vitesse | Qualité |
|
||||||
|
|---|---|---:|---:|---|---|
|
||||||
|
| **0.6B Base** | Damien (clone) | 4.0s | 18.4s | 0.22x RT | Bonne |
|
||||||
|
| **0.6B Base** | Élodie (clone) | 4.3s | 18.6s | 0.23x RT | Bonne |
|
||||||
|
| **1.7B CustomVoice** | Vivian (intégrée) | 6.1s | 37.8s | 0.16x RT | Très bonne |
|
||||||
|
| **1.7B CustomVoice** | Serena (intégrée) | 4.3s | 26.4s | 0.16x RT | Très bonne |
|
||||||
|
| **1.7B Base** | Damien (clone) | 5.0s | 30.9s | 0.16x RT | Très bonne |
|
||||||
|
| **1.7B Base** | Élodie (clone) | 3.8s | 23.7s | 0.16x RT | Très bonne |
|
||||||
|
|
||||||
|
### 2.2 Observations
|
||||||
|
|
||||||
|
- Le **0.6B est ~1.4x plus rapide** que le 1.7B (0.22x vs 0.16x RT)
|
||||||
|
- Le **clonage vocal** fonctionne bien avec les voix françaises (accent naturel)
|
||||||
|
- Les échantillons de référence doivent être **courts** (~3-10 secondes)
|
||||||
|
- L'audio est continu et complet sur toute la durée (RMS > 0 partout)
|
||||||
|
- Le 0.6B offre le **meilleur rapport qualité/vitesse** pour le clonage
|
||||||

## 3. Export du talker Qwen3-TTS pour le NPU
|
||||||
|
|
||||||
|
### 3.1 Architecture du modèle
|
||||||
|
|
||||||
|
Qwen3-TTS 0.6B est composé de 4 sous-modèles :
|
||||||
|
|
||||||
|
```
|
||||||
|
Texte + Voix ref → [Speaker Encoder] → x-vector
|
||||||
|
↓
|
||||||
|
[Talker LM] ← 28 couches Qwen3, 1024 hidden
|
||||||
|
↓ (identique à Qwen3-0.6B LLM)
|
||||||
|
[Code Predictor] ← 5 couches, 15 codebooks
|
||||||
|
↓
|
||||||
|
[Speech Decoder] ← ConvNet + Transformer
|
||||||
|
↓
|
||||||
|
Audio WAV
|
||||||

|
||||||
|
|
||||||
|
| Composant | Params | Rôle |
|
||||||
|
|---|---:|---|
|
||||||
|
| **Talker (LM)** | 754.8M | Génère les speech tokens (autorégressif) |
|
||||||
|
| Code Predictor | 141.6M | Prédit les 15 codebooks parallèles |
|
||||||
|
| Speaker Encoder | 8.9M | Extrait l'empreinte vocale |
|
||||||
|
| Speech Decoder | 114.3M | Décode les tokens en audio |
|
||||||
|
|
||||||
|
### 3.2 Conversion pour ExecuTorch + QNN
|
||||||
|
|
||||||
|
Le talker est **architecturalement identique** à Qwen3-0.6B :
|
||||||
|
- 28 couches Transformer
|
||||||
|
- hidden_size = 1024
|
||||||
|
- 16 attention heads, 8 KV heads
|
||||||
|
- head_dim = 128
|
||||||
|
- QK norm + RoPE theta 1M
|
||||||
|
- Seule différence : vocab_size = 3072 (codec) au lieu de 151936 (texte)
|
||||||
|
|
||||||
|
**Étapes de conversion** :
|
||||||
|
|
||||||
|
1. Extraction des poids du talker depuis le modèle HuggingFace
|
||||||
|
2. Renommage HF → Meta format (wq/wk/wv/wo, feed_forward.w1/w2/w3)
|
||||||
|
3. Remplacement de `tok_embeddings` par `codec_embedding` (3072x1024)
|
||||||
|
4. Suppression de `text_projection` et `text_embedding`
|
||||||
|
5. Patch du tokenizer pour clamper les IDs de calibration à [0, 3071]
|
||||||
|
6. Export via le pipeline ExecuTorch Qwen3-0.6B existant
|
||||||
|
|
||||||
|
**Résultat** : `.pte` de **286 Mo** généré en ~20 minutes.
|
||||||
|
|
||||||
|
### 3.3 Test sur le NPU Hexagon

|
||||||
|
| Tokens générés | 503 en 5.5s |
|
||||||
|
| Taille .pte | 286 Mo |
|
||||||
|
| Time to first token | 9 ms |
|
||||||
|
|
||||||
|
**Comparaison** :
|
||||||
|
|
||||||
|
| Backend | Talker decode (tok/s) | vs CPU |
|
||||||
|
|---|---:|---|
|

|
| **NPU Hexagon (ExecuTorch)** | **90.7** | **+4.1x** |
|
||||||
|
| CPU PC (PyTorch) | ~22 | baseline |
|

### 4.2 Mesure réelle du pipeline (CPU PC) et estimation NPU
|
||||||
|
|
||||||
|
**Phrase** : *"Bonjour, je suis là pour vous accompagner."* → 2.3s d'audio
|
||||||
|
|
||||||
|
| Composant | % temps | CPU PC | NPU tablette (estimé) |
|
||||||
|
|---|---:|---:|---:|
|
||||||
|
| **Talker (LM autorégressif)** | **87%** | 9.9s | **0.3s** (90.7 tok/s) |
|
||||||
|
| Speaker Encoder + Code Predictor + Decoder | 13% | 1.5s | ~1.5s |
|
||||||
|
| **Total** | 100% | **11.5s** | **~1.9s** |
|
||||||
|
| **Ratio temps réel** | | 0.20x (5x trop lent) | **1.24x RT** |
|
||||||
|
|
||||||
|
Le NPU transforme un pipeline **5x trop lent** en un pipeline **temps réel** en accélérant le talker (le goulot d'étranglement) de 3 tok/s à 90.7 tok/s.
|
||||||
|
|
||||||
|
### 4.3 Prérequis pour le déploiement complet

# Guide de calibration TTS Qwen3-TTS pour NPU
|
||||||
|
## ExecuTorch + QNN quantification calibrée
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. Pourquoi la calibration
|
||||||
|
|
||||||
|
Le fp16 brut (sans calibration) échoue sur les modèles TTS :
|
||||||
|
- **CP fp16** : produit du bruit (codebooks complètement faux)
|
||||||
|
- **Talker fp16** : produit du silence (tokens dans un mauvais régime)
|
||||||
|
- **Cause** : l'autoregression amplifie les erreurs de précision
|
||||||
|
|
||||||
|
La calibration observe les plages d'activation réelles du modèle et ajuste la quantification pour minimiser la distorsion. C'est la technique utilisée pour le LLM Qwen3-0.6B (93 tok/s sur NPU).
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 2. Phrases de calibration
|
||||||
|
|
||||||
|
**Fichier** : `models_qnn/calibration_phrases.json`
|
||||||
|
|
||||||
|
10 langues × 5 phrases = 50 phrases couvrant :
|
||||||
|
- Chinois, Anglais, Allemand, Espagnol, Japonais
|
||||||
|
- Français, Coréen, Russe, Italien, Portugais
|
||||||
|
|
||||||
|
Chaque phrase couvre des phonèmes variés, prosodie (questions, exclamations), et cas difficiles.
|
||||||
|
|

|
||||||
|
|
||||||
|
## 3. Collecte des tenseurs de calibration
|
||||||
|
|
||||||
|
### Prérequis
|
||||||
|
- Python 3.10 dans `/opt/Kazeia/qnn_venv/`
|
||||||
|
- Modèle Qwen3-TTS dans le cache HuggingFace
|
||||||
|
- Speaker embedding Damien dans `models_qnn/qwen3-tts-embeddings/`
|
||||||
|
|
||||||
|
### Commande
|
||||||
|
```bash
|

|
||||||
|
Le script :
|
||||||
|
1. Charge le modèle Qwen3-TTS complet en fp32
|
||||||
|
2. Hook le `talker.model.forward` et `code_predictor.model.forward`
|
||||||
|
3. Pour chaque phrase, lance `model.generate()` avec le pipeline complet (sampling, tts_pad, voice cloning)
|
||||||
|
4. Sauvegarde les `inputs_embeds` de chaque forward pass
|
||||||
|
|
||||||
|

|
|
||||||
|
# 1. Créer le wrapper (même que pour l'export fp16)
|
||||||
|
wrapper = TalkerKVWrapper(model.talker.model, model.talker.codec_head)
|
||||||
|
|
||||||
|
# 2. torch.export
|
||||||
|
exported = torch.export.export(wrapper, example_inputs, strict=False)
|
||||||
|
|
||||||
|
# 3. Préparer la quantification
|
||||||
|
quantizer = QnnQuantizer()
|
||||||
|
quantizer.set_quant_config(QuantDtype.use_16a8w) # 16-bit activations, 8-bit weights
|
||||||
|
prepared = prepare_pt2e(exported, quantizer)
|
||||||
|
|
||||||
|
# 4. Calibration : rejouer les tenseurs collectés
|
||||||
|
for tensor_file in calibration_files:
|
||||||
|
inputs = torch.load(tensor_file)
|
||||||
|
prepared(*rebuild_full_inputs(inputs))
|
||||||
|
|
||||||
|
# 5. Convertir
|
||||||
|
quantized = convert_pt2e(prepared)
|
||||||
|
|
||||||
|
# 6. Export QNN
|
||||||
|
edge = to_edge_transform_and_lower_to_qnn(quantized, ...)
|
||||||
|
pte = edge.to_executorch()
|
||||||
|

|
||||||
|
|
||||||
|
### Schémas de quantification à tester
|
||||||
|
| Schéma | Poids | Activations | KV cache | Taille estimée |
|
||||||
|
|--------|-------|-------------|----------|----------------|
|
||||||
|

## 6. Wrappers PyTorch validés
|
||||||
|
|
||||||
|
### Talker wrapper (28 layers, M-RoPE)
|
||||||
|
- Inputs : `[emb(1,1,1024), mask(1,1,1,200), cos(1,1,128), sin(1,1,128), 56×kv(1,8,199,128)]`
|
||||||
|
- Outputs : `[hidden(1,1,1024), logits(1,1,3072), 56×kv(1,8,200,128)]`
|
||||||
|
- Validé identique à PyTorch (diff logits < 0.00006)
|
||||||
|
- M-RoPE pré-calculé avec `apply_interleaved_rope` pour les 3 axes (identiques en TTS)
|
||||||
|
|
||||||
|
### CP wrapper (5 layers, RoPE standard)
|
||||||
|
- Inputs : `[emb(1,1,1024), mask(1,1,1,17), cos(1,1,128), sin(1,1,128), 10×kv(1,8,16,128)]`
|
||||||
|
- Outputs : `[hidden(1,1,1024), head_logits(1,15,2048), 10×kv(1,8,17,128)]`
|
||||||
|
- Validé 15/15 match vs PyTorch
|
||||||
|
- Inclut projection + 15 heads dans le même modèle
|
||||||
|
|
||||||
|
### Points critiques (bugs trouvés et corrigés)
|
||||||
|
1. **q_norm / k_norm** : RMSNorm sur Q et K avant rotary — obligatoire
|
||||||
|
2. **M-RoPE interleaved** : le talker utilise un rotary multimodal à 3 axes
|
||||||
|
3. **WrapWithSetGradEnabled** : contourné en pré-calculant cos/sin
|
||||||
|
4. **tts_pad après texte** : le modèle attend tts_pad_embed (pas des zeros) après l'EOS texte
|
||||||

# Guide GPU Adreno pour TTS Qwen3-TTS
|
||||||
|
## ONNX Runtime QNN GPU Backend — Audio parfait, tokens identiques au CPU
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. Résumé
|
||||||
|
|
||||||
|
Le GPU Adreno 830 produit un audio TTS **parfait** via ONNX Runtime QNN avec le backend GPU (`libQnnGpu.so`). Contrairement au NPU (HTP) qui quantifie et détruit la qualité, le GPU fait du **fp32/fp16 natif IEEE-754** sans quantification.
|
||||||
|
|
||||||
|
**Résultat :** tokens identiques au CPU (1995, 215, 212...), EOS naturel, audio impeccable.
|
||||||
|
|
||||||
|
**Vitesse :** 124-131ms/step (identique au CPU — pas de gain de vitesse dû à l'overhead de transfert mémoire par token).

|
||||||
|
|
||||||
|
// APRÈS (GPU Adreno)
|
||||||
|
val gpuPath = "$nativeLibDir/libQnnGpu.so"
|
||||||
|
val opts = OrtSession.SessionOptions()
|
||||||
|
opts.addQnn(mapOf("backend_path" to gpuPath))
|
||||||
|
talkerKv = ortEnv!!.createSession(cpuOnnx.absolutePath, opts)
|
||||||
|
talkerUsesInt64Pos = false // CRITIQUE: GPU QNN exige int32, pas int64
|
||||||
|
```
|
||||||
|
|
||||||
|
### Point critique : `talkerUsesInt64Pos = false`
|
||||||
|
Le GPU QNN backend n'accepte pas les tenseurs `int64` pour `position_ids`. L'erreur sinon :
|
||||||
|
```
|
||||||
|
ORT_INVALID_ARGUMENT: Unexpected input data type. Actual: (tensor(int64)), expected: (tensor(int32))
|
||||||
|
```
|
||||||
|
Le CPU ONNX accepte `int64`, le HTP aussi, mais le GPU non. Il faut envoyer `int32`.
|
||||||
|
|
||||||
|
### Code de création du tenseur position (dans `runTalkerStep`) :
|
||||||
|
```kotlin
|
||||||
|
val posTensor = if (talkerUsesInt64Pos) {
|
||||||
|
OnnxTensor.createTensor(env, LongBuffer.wrap(longArrayOf(pos.toLong())), longArrayOf(1))
|
||||||
|
} else {
|
||||||
|
OnnxTensor.createTensor(env, IntBuffer.wrap(intArrayOf(pos)), longArrayOf(1))
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|

|
||||||
|
|
||||||
|
## 3. Bibliothèques nécessaires
|
||||||
|
|
||||||
|
### Dans `app/src/main/jniLibs/arm64-v8a/` :
|
||||||
|
|
||||||
|
| Fichier | Source | Taille |
|
||||||
|
|---------|--------|--------|
|
||||||
|
| `libQnnGpu.so` | QNN SDK `lib/aarch64-android/` | 6.1 MB |
|
||||||
|
| `libQnnGpuNetRunExtensions.so` | QNN SDK `lib/aarch64-android/` | ~1 MB |
|
||||||
|
| `libQnnGpuProfilingReader.so` | QNN SDK `lib/aarch64-android/` | ~0.5 MB |
|
||||||
|
|
||||||
|
### Commande pour copier depuis le QNN SDK :
|
||||||
|
```bash
|
||||||
|
QNN_SDK=/opt/Kazeia/qnn_sdk_242/qairt/2.42.0.251225
|
||||||
|
cp $QNN_SDK/lib/aarch64-android/libQnnGpu*.so \
|
||||||
|
kazeia-android/app/src/main/jniLibs/arm64-v8a/
|
||||||
|
```
|
||||||
|
|
||||||
|
### Dépendances système (déjà présentes sur Android) :
|
||||||
|
- `libEGL.so` — OpenGL ES context
|
||||||
|
- `libGLESv2.so` — OpenGL ES 2.0
|
||||||
|
- `libOpenCL.so` — déjà dans `/vendor/etc/public.libraries.txt` sur OnePlus Pad 2
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 4. Modèle ONNX
|
||||||
|
|
||||||
|
**Aucune re-exportation nécessaire.** Le même modèle ONNX CPU fonctionne sur GPU :
|
||||||
|
- `talker_kv_cpu/model.onnx` (1.77 GB) — utilisé tel quel
|
||||||
|
- Le GPU backend d'ONNX Runtime QNN compile le graph ONNX à la volée
|
||||||
|
|
||||||
|
### Pas de cache GPU
|
||||||
|
Le context caching (`qnn_context_cache_enable`) ne fonctionne PAS avec le backend GPU d'ONNX Runtime (contrairement au HTP). Chaque session recompile le graph (~2.5s de chargement).
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 5. Pourquoi le GPU fonctionne mais pas le NPU
|
||||||
|
|
||||||
|
| Aspect | NPU (HTP) | GPU (Adreno) |
|
||||||
|
|--------|-----------|--------------|
|
||||||
|
| Précision | INT8/INT16 quantifié | FP16/FP32 natif IEEE-754 |
|
||||||
|
| Quantification | Automatique, destructive | Aucune |
|
||||||
|
| Codebook argmax | Changé par la quantification | Identique au CPU |
|
||||||
|
| Audio TTS | Bruit / silence / inintelligible | **Parfait** |
|
||||||
|
| Vitesse | ~20ms/step (inutilisable) | ~130ms/step |
|
||||||
|
|
||||||
|
Le TTS sélectionne des codebooks par `argmax` sur 2048 valeurs. La moindre erreur de quantification (NPU) change le codebook sélectionné et cascade dans l'autoregression. Le GPU fait du vrai fp32 → mêmes codebooks → même audio.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 6. Performance
|
||||||
|
|
||||||
|
| Métrique | CPU fp32 | GPU fp16/fp32 |
|
||||||
|
|----------|---------|---------------|
|
||||||
|
| Chargement | 2.5s | 2.8s (+graph compile) |
|
||||||
|
| Talker/step | 130ms | 124-131ms |
|
||||||
|
| Audio | Parfait | Parfait |
|
||||||
|
| RTF | 7.0 | 7.0 |
|
||||||
|
|
||||||
|
**Pas de gain de vitesse.** Le GPU est memory-bound pour les petits batch sizes (1 token). L'overhead de transfert CPU→GPU→CPU par step annule le gain de calcul parallèle du GPU.
|
||||||
|
|
||||||
|
**Utilité :** le GPU libère les cœurs CPU pour d'autres tâches (CP, UI, audio playback). En mode streaming, le talker sur GPU + CP sur CPU fonctionneraient en parallèle.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 7. Dépendances Gradle
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
// Déjà présent pour le reste du pipeline TTS
|
||||||
|
implementation("com.microsoft.onnxruntime:onnxruntime-android-qnn:1.24.3")
|
||||||
|
```
|
||||||
|
|
||||||
|
Pas de dépendance supplémentaire. Le QNN GPU backend est inclus dans l'AAR ONNX Runtime.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 8. Erreurs courantes
|
||||||
|
|
||||||
|
### `Unexpected input data type. Actual: (tensor(int64)), expected: (tensor(int32))`
|
||||||
|
→ Mettre `talkerUsesInt64Pos = false` pour envoyer `position_ids` en `int32`.
|
||||||
|
|
||||||
|
### `Cannot Open QNN library libQnnGpu.so`
|
||||||
|
→ Copier `libQnnGpu.so` dans `jniLibs/arm64-v8a/`.
|
||||||
|
|
||||||
|
### `Execution failed for method: forward` (ExecuTorch)
|
||||||
|
→ Le JNI ExecuTorch ne fonctionne PAS avec le GPU QNN depuis l'app (problème de contexte GPU). Utiliser ONNX Runtime à la place.
|
||||||
|
|
||||||
|
### Pas de cache GPU
|
||||||
|
→ Normal. Le QNN GPU backend ne supporte pas le context caching. Le graph est recompilé à chaque session (~2.5s).
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 9. Architecture finale recommandée
|
||||||
|
|
||||||
|
```
|
||||||
|
LLM Qwen3-0.6B → NPU HTP (93 tok/s, INT4 calibré) — ExecuTorch
|
||||||
|
Whisper STT → NPU HTP (INT8 calibré) — ONNX Runtime QNN
|
||||||
|
TTS Talker → GPU Adreno (fp32 natif) — ONNX Runtime QNN
|
||||||
|
TTS CP → CPU fp32 — ONNX Runtime
|
||||||
|
TTS Decoder → NPU HTP — ONNX Runtime QNN
|
||||||
|
Silero VAD → CPU (1.8 Mo) — ONNX Runtime
|
||||||
|
```
|
||||||
|
|
||||||
|
Chaque composant sur le backend optimal : NPU pour ce qui tolère la quantification, GPU pour le TTS qui exige la précision, CPU pour le reste.

# Guide Hexagon NPU FP16 natif pour TTS
|
||||||
|
## llama.cpp + ggml-hexagon + HMX FP16 — 47.8 tok/s
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. Pourquoi ça marche
|
||||||
|
|
||||||
|
Le QNN SDK quantifie automatiquement en int8/int16 → détruit le TTS.
|
||||||
|
Le ggml-hexagon contourne le QNN SDK et accède directement aux unités HMX
|
||||||
|
du Hexagon DSP en **vrai FP16 IEEE-754** via des kernels reverse-engineerés
|
||||||
|
(htp-ops-lib, Zixu Hao, EuroSys 2026).
|
||||||
|
|
||||||
|
| Approche | Précision | Vitesse | Audio TTS |
|
||||||
|
|----------|-----------|---------|-----------|
|
||||||
|
| QNN SDK HTP | int8/int16 quantifié | ~11ms/step | Silence/bruit |
|
||||||
|
| QNN SDK GPU | fp16 IEEE-754 | ~130ms/step | Parfait |
|
||||||
|
| **ggml-hexagon HMX** | **fp16 IEEE-754** | **~21ms/step** | **À tester** |
|
||||||
|
| ONNX Runtime CPU | fp32 | ~107ms/step | Parfait |
|
||||||
|
|
||||||
|

```
|
||||||
|
|
||||||
|
## 3. Conversion talker → GGUF F16
|
||||||
|
|
||||||
|
Le talker TTS est un Qwen3 standard (28 layers, 1024 dim, q_norm/k_norm).
|
||||||
|
On extrait ses poids et crée un GGUF compatible.
|
||||||
|
|
||||||
|
### Script : extraction des poids
|
||||||
|
```python
|
||||||
|
# Extraire les poids du talker dans un format HF standalone
|
||||||
|
state_dict = {}
|
||||||
|
for name, param in inner.named_parameters():
|
||||||
|
if name not in skip_set:
|
||||||
|
state_dict[f"model.{name}"] = param.detach().clone()
|
||||||
|
state_dict["model.embed_tokens.weight"] = inner.codec_embedding.weight.detach().clone()
|
||||||
|
state_dict["lm_head.weight"] = codec_head.weight.detach().clone()
|
||||||
|
```
|
||||||
|
|
||||||
|
### Script : création GGUF manuelle
|
||||||
|
```python
|
||||||
|
from gguf import GGUFWriter, GGMLQuantizationType
|
||||||
|
writer = GGUFWriter("talker_f16.gguf", "qwen3")
|
||||||
|
# ... add metadata (hidden_size, num_layers, etc.)
|
||||||
|
# ... add tensors with F16 weights, F32 norms
|
||||||
|
writer.add_tokenizer_model("none") # pas de tokenizer texte
|
||||||
|
```
|
||||||
|
|
||||||

## 4. Déploiement sur tablette
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Push binaries
|
||||||
|
DST=/data/local/tmp/kazeia/llama-hex
|
||||||
|
adb shell "mkdir -p $DST"

|
||||||
|
-mmp 0 -ngl 99 -pg 1,5"
|
||||||
|
```
|
||||||
|
|
||||||
|
## 5. Benchmark (SM8750, Hexagon v79)
|
||||||
|
|
||||||
|
```
|
||||||
|
| model | size | backend | test | tok/s |
|
||||||
|
|-----------------|----------|-------------|----------|----------|
|
||||||
|
| qwen3 0.6B F16 | 852 MiB | OpenCL,HTP | pp512 | 464 ± 16 |
|
||||||
|
| qwen3 0.6B F16 | 852 MiB | OpenCL,HTP | tg128 | 46.4 ± 1 |
|
||||||
|
| qwen3 0.6B F16 | 852 MiB | OpenCL,HTP | pp1+tg5 | 47.8 ± 1 |
|
||||||
|
```
|
||||||
|
|
||||||
|
**47.8 tok/s = ~21ms/step** (vs 107ms CPU = 5× plus rapide)
|
||||||
|
|
||||||
|
## 6. Prochaines étapes
|
||||||
|
|
||||||
|
### Runner custom pour embeddings TTS
|
||||||
|
llama.cpp API supporte `llama_batch.embd` pour envoyer des embeddings
|
||||||
|
au lieu de token IDs. Il faut écrire un petit runner C++ qui :
|
||||||
|
1. Charge le GGUF avec le backend hexagon
|
||||||
|
2. Accepte des embeddings composites (1024 floats) via stdin/fichier
|
||||||
|
3. Retourne les logits (3072 floats) sur stdout/fichier
|
||||||
|
4. Gère le KV-cache entre les steps
|
||||||
|
|
||||||
|
### Intégration dans l'app
|
||||||
|
- Le runner tourne en subprocess root (comme le LLM)
|
||||||
|
- L'app envoie les embeddings composites et lit les logits
|
||||||
|
- Le sampling (temp=0.9, top_k=50) reste sur CPU côté app
|
||||||
|
|
||||||
|
### CP sur Hexagon NPU
|
||||||
|
- Même approche : convertir le CP (5 layers) en GGUF F16
|
||||||
|
- 5 layers → encore plus rapide que le talker
|
||||||
|
- Estimation : ~5ms pour les 17 steps CP

|
||||||
|
|
||||||
|
## 1. Point de départ
|
||||||
|
|
||||||
|
### Modèle choisi
|
||||||
|
**Qwen3-TTS-12Hz-0.6B-Base** (Alibaba/Qwen)
|
||||||
|
- 757M paramètres (talker) + 83M (code predictor) + decoder conv
|
||||||
|
- 12 Hz codec (12 frames/seconde), 16 codebooks RVQ par frame
|
||||||
|
- Voice cloning obligatoire via x-vector (pas de voix built-in)
|
||||||
|
- 10 langues : français, anglais, allemand, espagnol, japonais, chinois, coréen, russe, italien, portugais
|
||||||
|
|
||||||
|
### Architecture du pipeline
|
||||||
|
```
|
||||||
|
Texte → Tokenizer → Prefill (10 tokens)
|
||||||
|
↓
|
||||||
|
[Boucle autoregressive × ~50 steps]
|
||||||
|
│ Talker (28 layers) → logits CB0 + hidden state
|
||||||
|
│ Sampling (temp=0.9, top_k=50, rep_penalty=1.05)
|
||||||
|
│ Code Predictor (5 layers × 17 passes) → CB1-CB15
|
||||||
|
│ Somme 16 embeddings + texte trailing → next input
|
||||||
|
└→ [Fin sur EOS token 2150]
|
||||||
|
↓
|
||||||
|
VQ Decode → Speech Decoder (conv) → Audio PCM 24kHz
|
||||||
|
```

|
## 2. Bugs critiques découverts et corrigés
|
||||||
|
|
||||||
|
### Bug 1 : tts_pad manquant (LE bug critique)
|
||||||
|
- **Symptôme** : le modèle ne générait JAMAIS le token EOS, produisant 100+ tokens sans arrêt
|
||||||
|
- **Cause** : après épuisement des tokens texte, notre code envoyait des zéros. Le modèle Python envoie `tts_pad_embed`
|
||||||
|
- **Impact** : sans ce fix, aucun pipeline TTS ne pouvait fonctionner correctement
|
||||||
|
- **Correction** : une ligne → `nextEmbed = sumEmb(codecSum, padE)` au lieu de `nextEmbed = codecSum`
|
||||||
|
|
||||||
|
### Bug 2 : q_norm / k_norm oubliés dans le CP
|
||||||
|
- **Symptôme** : le CP exporté en KV-cache divergeait complètement au step 2
|
||||||
|
- **Cause** : l'attention du CP applique RMSNorm sur Q et K avant le rotary embedding. Notre wrapper manuel l'oubliait
|
||||||
|
- **Impact** : 0/15 codebooks corrects
|
||||||
|
- **Correction** : ajout de `attn.q_norm()` et `attn.k_norm()` dans le wrapper
|
||||||
|
|
||||||
|
### Bug 3 : Role prefill (assistant vs user)
|
||||||
|
- **Symptôme** : tokens incorrects dès le prefill
|
||||||
|
- **Cause** : le prefill utilisait le token "user" au lieu de "assistant" en mode voice cloning
|
||||||
|
- **Correction** : `TOKEN_ASSISTANT = 1042`
|
||||||
|
|
||||||
|
### Bug 4 : M-RoPE multimodal du talker
|
||||||
|
- **Symptôme** : le talker exporté produisait des logits différents du PyTorch
|
||||||
|
- **Cause** : le talker utilise M-RoPE avec `mrope_section=[24,20,20]` et `interleaved=True`, pas le RoPE standard
|
||||||
|
- **Correction** : pré-calcul des cos/sin avec `apply_interleaved_rope` et passage en inputs
|
||||||
|
|
||||||
|
### Bug 5 : DSP partagé (hexagon runner vs QNN decoder)
|
||||||
|
- **Symptôme** : le décodeur QNN crashait avec erreur 6031 après l'utilisation du runner hexagon
|
||||||
|
- **Cause** : le runner hexagon gardait une session HTP ouverte qui bloquait le QNN decoder
|
||||||
|
- **Correction** : QUIT le runner et `pkill` avant le décodage
|
||||||
|
|

## 3. Tentatives d'accélération NPU — Échecs instructifs
|
||||||
|
|
||||||
|
### 3.1 ONNX Runtime QNN EP (backend HTP)
|
||||||
|
| Config | Résultat | Cause |
|
||||||
|
|--------|----------|-------|
|
||||||
|
| Talker HTP default | EOS prématuré (1.4-2.2s) | Quantification int8/int16 automatique |
|
||||||
|
| Talker HTP "fp16" | Idem | L'option `enable_htp_fp16_precision` n'a aucun effet |
|
||||||
|
| CP HTP default | Pas d'EOS (185 tokens) | Codebooks corrompus |
|
||||||
|
| CP HTP fp16 | Idem | Même quantification destructive |
|
||||||
|
|
||||||
|
**Conclusion** : ONNX Runtime QNN EP quantifie TOUJOURS en int8/int16 via le QNN SDK, même avec les flags fp16. Le QNN SDK ne fait PAS de vrai fp16 IEEE-754.
|
||||||
|
|
||||||
|
### 3.2 ExecuTorch .pte (backend HTP)
|
||||||
|
| Config | Résultat | Cause |
|
||||||
|
|--------|----------|-------|
|
||||||
|
| Talker fp16 .pte | Silence (EOS OK mais audio vide) | fp16 HTP ≠ vrai fp16 |
|
||||||
|
| CP fp16 .pte | Bruit | Codebooks totalement faux |
|
||||||
|
| Talker 16a8w calibré | Inintelligible (EOS OK, 102 tokens) | Même avec calibration, pas assez précis |
|
||||||
|
| Talker split (NPU backbone + CPU lm_head) | EOS prématuré | Hidden states NPU déjà corrompus |
|
||||||
|
| Talker SmoothQuant + split | Inintelligible | SmoothQuant ne corrige pas la quantification HTP |
|
||||||
|
|
||||||
|
**Conclusion** : le HTP (via QNN SDK) est incompatible avec les modèles TTS autoregressifs. La quantification détruit la précision des codebooks, même en fp16, même avec calibration, même avec SmoothQuant.
|
||||||
|

### 3.3 GPU Adreno (ONNX Runtime QNN)
|
||||||
|
| Config | Résultat | Cause |
|
||||||
|
|--------|----------|-------|
|
||||||
|
| Talker GPU fp16 | **Audio parfait, tokens identiques** | Vrai fp16 IEEE-754 natif |
|
||||||
|
| Talker GPU fp32 | Audio parfait | fp32 natif |
|
||||||
|
|
||||||
|
**Mais** : vitesse GPU = vitesse CPU (130ms/step). L'overhead de transfert CPU↔GPU par token annule le gain. **Pas d'accélération.**
|
||||||
|
|
||||||
|
**Conclusion** : le GPU prouve que le vrai fp16 fonctionne pour le TTS. Le problème est le QNN SDK, pas le hardware.

## 4. La percée : ggml-hexagon (HMX FP16 natif)
|
||||||
|
|
||||||
|
### 4.1 Découverte
|
||||||
|
Le QNN SDK ne fait pas du vrai fp16 sur le HTP. Mais le hardware HMX (Hexagon Matrix eXtension) supporte nativement le fp16 IEEE-754. Le projet `htp-ops-lib` (Zixu Hao, EuroSys 2026) a reverse-engineeré les instructions HMX non documentées et les a intégrées dans llama.cpp via le backend `ggml-hexagon`.
|
||||||
|
|
||||||
|
### 4.2 Validation
|
||||||
|
```
|
||||||
|
Talker GGUF F16 sur Hexagon HMX :
|
||||||
|
- Top codec token : NPU=1739, CPU=1739 → MATCH EXACT
|
||||||
|
- Top 5 identiques : [1739, 1130, 808, 468, 663]
|
||||||
|
- Max logit diff : 0.0226
|
||||||
|
- Corrélation : 0.999998
|
||||||
|
- Vitesse : 48 tok/s = ~21ms/step (benchmark)
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4.3 Implémentation
|
||||||
|
- **Conversion GGUF** : extraction des poids du talker en format Qwen3 GGUF F16 (852 MB)
|
||||||
|
- **Build** : llama.cpp compilé avec le toolchain Docker `ghcr.io/snapdragon-toolchain/arm64-android:v0.3`
|
||||||
|
- **Runner C++** : `tts-talker.cpp` (talker) et `tts-cp-runner.cpp` (CP), communication via Unix domain sockets
|
||||||
|
- **IPC** : sockets Unix entre l'app Kotlin et les runners root (chmod 666)
|
||||||
|
- **KV-cache** : talker persistant entre les tokens, CP reset via `llama_memory_clear` à chaque appel
|
||||||
|
|
||||||
|
### 4.4 Architecture finale

## 5. Évolution des performances
|

|
|
||||||
|
| Étape | Talker | CP | Decode | RTF | Date |
|
||||||
|
|-------|--------|-----|--------|-----|------|
|
||||||
|
| CPU pur (ONNX, 4 threads) | 130ms | 350ms (fullseq) | 3s NPU | 7.0 | 01/04 |
|
||||||
|
| + 6 threads + CP KV-cache | 107ms | 202ms | 3s | 4.95 | 01/04 |
|

|
||||||
|
| + memory_clear CP | 27ms | 85ms | 3.5s | **2.42** | 02/04 |
|
||||||
|
|
||||||
|
**Gain total : RTF 7.0 → 2.42 = 2.9× plus rapide**

|
## 6. Tentatives avortées ou en suspens
|
||||||
|
|
||||||
|
### Streaming (play pendant la génération)
|
||||||
|
- **Problème** : le décodeur QNN et les runners hexagon ne peuvent pas coexister sur le DSP
|
||||||
|
- **Status** : le `synthesizeAndPlay` en mode streaming bloque sur le decode QNN
|
||||||
|
- **Solution possible** : decoder sur GPU Adreno ou CPU (pas le HTP)
|
||||||
|
|
||||||
|
### CP sur le même process que le talker (dual-model)
|
||||||
|
- **Problème** : deux contextes llama dans le même process se marchent dessus sur le HTP
|
||||||
|
- **Solution** : deux processes séparés (fonctionnel)
|
||||||
|
|
||||||
|
### NeuTTS Air
|
||||||
|
- **Testé** : chargement OK, génération RTF 1.04 sur PC x86
|
||||||
|
- **Status** : non intégré, qualité français à valider
|
||||||
|
- **Intérêt** : single codebook FSQ → potentiellement compatible NPU quantifié
|
||||||
|
|
||||||
|
### Quantification calibrée (16a8w)
|
||||||
|
- **Données** : 2618 tenseurs talker + 39270 CP collectés (10 langues, 50 phrases)
|
||||||
|
- **Status** : testé, inintelligible. La calibration ne suffit pas pour le TTS RVQ

## 8. Leçons apprises
|
||||||
|
|
||||||
|
1. **Le QNN SDK ment sur le fp16** — il quantifie toujours en int8/int16 même avec `use_fp16=True`. Le vrai fp16 n'est accessible que via les instructions HMX reverse-engineerées (ggml-hexagon)
|
||||||
|
|
||||||
|
2. **Le GPU Adreno fait du vrai fp16** — tokens identiques au CPU, prouvant que le fp16 IEEE-754 est suffisant pour le TTS. C'est le GPU qui nous a donné la preuve que le problème était le QNN SDK, pas la précision fp16
|
||||||
|
|
||||||
|
3. **Les modèles TTS RVQ sont incompatibles avec la quantification** — contrairement aux LLM qui tolèrent int4, le TTS avec 16 codebooks RVQ est détruit par la moindre erreur de quantification. L'argmax sur 2048 valeurs avec des marges fines ne pardonne pas
|
||||||
|
|
||||||
|
4. **ggml-hexagon est la clé** — les kernels HMX reverse-engineerés de htp-ops-lib donnent accès à 12 TFLOPS fp16 natif, contournant complètement le QNN SDK. Le même NPU, des résultats radicalement différents
|
||||||
|
|
||||||
|
5. **Deux processes sur le même HTP fonctionnent** — contrairement au dual-model dans le même process, deux processes séparés avec chacun leur contexte HTP coexistent
|
||||||
|
|
||||||
|
6. **Les sockets Unix sont 5× plus rapides que les fichiers** — IPC par fichier ajoutait ~50ms par call, les sockets réduisent à ~1ms
|
||||||
|
|
||||||
|
7. **Le DSP est un goulot de partage** — le runner hexagon et le décodeur QNN ne coexistent pas bien, même séquentiellement. Le streaming est bloqué par ce conflit
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 9. État actuel et prochaines étapes
|
||||||
|
|
||||||
|
### Performance actuelle
|
||||||
|
- **RTF 2.42** (10s pour 4s audio, hors cold start)
|
||||||
|
- **Audio parfait**, tokens identiques au CPU, EOS naturel
|
||||||
|
- **Voice cloning** fonctionnel (voix Damien)
|
||||||
|
- **Cold start** : ~28s (chargement runners + modèles)
|
||||||
|
|
||||||
|
### Architecture cible compatible Unity
|
||||||
|
```
|
||||||
|
LLM Qwen3-0.6B → NPU HTP INT4 (ExecuTorch, 93 tok/s)
|
||||||
|
Whisper STT → NPU HTP (ONNX Runtime QNN)
|
||||||
|
TTS Talker → Hexagon HMX FP16 (ggml-hexagon, 37 tok/s)
|
||||||
|
TTS CP → Hexagon HMX FP16 (ggml-hexagon, 11 tok/s)
|
||||||
|
TTS Decoder → NPU HTP (ONNX Runtime QNN, séquentiel après runners)
|
||||||
|
Silero VAD → CPU
|
||||||
|
Unity Avatar 3D → GPU Adreno 100% libre
|
||||||
|
```
|
||||||
|
|
||||||
|
### Optimisations restantes
|
||||||
|
1. **Streaming** : decoder sur CPU ou GPU pour éviter le conflit DSP → premier son à ~7s au lieu de ~10s
|
||||||
|
2. **Cold start** : pré-charger les runners au boot de l'app, pas à chaque génération
|
||||||
|
3. **CP optimisation** : batched prefill (2 tokens), head matmuls sur NPU
|
||||||
|
4. **BPE tokenizer** : remplacer les phrase_embeds pré-calculés par un vrai tokenizer
|
||||||
|
5. **Multi-voix** : supporter plusieurs x-vectors pour différents personnages

## 1. Modele choisi
|
||||||
|
|
||||||
|
**Qwen3-TTS-12Hz-0.6B-Base** (Alibaba/Qwen)
|
||||||
|
- 0.6B parametres, 12 Hz codec (12 tokens/seconde audio)
|
||||||
|
- 16 codebooks par frame audio (hierarchiques)
|
||||||
|
- Architecture : Talker (28 layers, 1024 dim) + Code Predictor (5 layers, 1024 dim) + Speech Decoder (conv)
|
||||||
|
- Voice cloning obligatoire via x-vector (le modele Base n'a aucune voix built-in)

|
## 2. Architecture du pipeline
|
||||||
|
|
||||||
|
```
|
||||||
|
Texte → Tokenizer → [Prefill] → Talker → CB0 token
|
||||||
|
↓
|
||||||
|
Code Predictor → CB1-CB15
|
||||||
|
↓
|
||||||
|
16 codebooks → VQ Decode → Audio PCM
|
||||||
|
```
|
||||||
|
|
||||||
|
### Etapes detaillees :
|
||||||
|
|
||||||
|
1. **Prefill** (10 tokens) : `<|im_start|>assistant\n` + 4 tokens controle (think, think_bos, lang_fr, think_eos) + speaker embedding + bos + premier token texte
|
||||||
|
|
||||||
|
2. **Generation interleaved** (boucle autoregressive) :
|
||||||
|
- Talker forward → logits CB0 + hidden state
|
||||||
|
- Code Predictor (hidden, CB0_emb) → CB1-CB15 autoregressivement (15 steps)
|
||||||
|
- Somme 16 embeddings codebooks + texte trailing → input suivant du talker
|
||||||
|
- Sampling (temp=0.9, top_k=50, repetition_penalty=1.05)
|
||||||
|
- Arret sur EOS (token 2150)
|
||||||
|
|
||||||
|
3. **Decodage** : VQ lookup → pre_conv → preprocessor → conv_decoder → audio 24kHz

||||||

## 3. Reussites
|
||||||
|
|
||||||
|
### 3.1 Pipeline fonctionnel complet
|
||||||
|
- Audio de bonne qualite, voix clonee reconnaissable
|
||||||
|
- EOS naturel (le modele s'arrete seul)
|
||||||
|
- Fonctionne pour des phrases de longueur variable
|
||||||
|
- **RTF 7.1** (28s pour 4s audio)
|
||||||
|
|
||||||
|
### 3.2 Export ONNX valide
|
||||||
|
- **Talker KV-cache** : 1.77 GB, 28 layers, shapes fixes (KV=199), valide identique a PyTorch
|
||||||
|
- **CP fullseq** : 420 MB, 5 layers, shapes dynamiques, causal mask, 15/15 match vs PyTorch
|
||||||
|
- **CP KV-cache** : 420 MB, shapes fixes (KV=16), valide 15/15 match vs PyTorch
|
||||||
|
- **Decoder** (pre_conv + preprocessor + conv_decoder) : fonctionne sur NPU via ONNX Runtime QNN EP
|
||||||
|
|
||||||
|
### 3.3 Decodeur sur NPU
|
||||||
|
- pre_conv, preprocessor, conv_decoder : tous sur QNN NPU
|
||||||
|
- ~3s pour decoder un chunk de 60 tokens
|
||||||
|
- Pas de degradation de qualite
|
||||||
|
|
||||||
|
### 3.4 Bug critique trouve et corrige : tts_pad
|
||||||
|
- **Decouverte** : apres epuisement des tokens texte, le modele Python ajoute `tts_pad_embed` (pas des zeros)
|
||||||
|
- **Impact** : sans tts_pad, le modele ne converge JAMAIS vers EOS (100+ tokens sans arret)
|
||||||
|
- **Correction** : une ligne changee dans la boucle de generation
|
||||||
|
- C'etait LE bug qui empechait le pipeline de fonctionner correctement
|
||||||
|
|
||||||
|
### 3.5 Bug CP corrige : QK normalization
|
||||||
|
- Le CP utilise RMSNorm sur Q et K avant le rotary embedding (`q_norm`, `k_norm`)
|
||||||
|
- Notre premiere implementation manuelle de l'attention les oubliait → divergence totale au step 2
|
||||||
|
- Correction : ajout de `attn.q_norm()` et `attn.k_norm()` dans le wrapper
|
||||||
|
|
||||||
|
### 3.6 Export ExecuTorch .pte
|
||||||
|
- CP KV-cache exporte en .pte avec QNN fp16 backend (SM8750)
|
||||||
|
- **55ms pour 17 steps NPU** (vs 5.5s CPU) via le runner C++ standalone
|
||||||
|
- Pipeline d'export : torch.export → to_edge_transform_and_lower_to_qnn → .pte
|
||||||
|
- Contournement du bug `WrapWithSetGradEnabled` : pre-calcul des rotary cos/sin
|
||||||
|
|
||||||
|
### 3.7 JNI ExecuTorch integre dans l'app
|
||||||
|
- `libexecutorch.so` (49MB) compile pour arm64 avec QNN backend
|
||||||
|
- Classes Java ExecuTorch compilees dans un JAR local
|
||||||
|
- Dependances fbjni + soloader resolues
|
||||||
|
- **CP NPU via JNI : 79ms/step** (vs 353ms CPU = 4.5x plus rapide)
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 4. Echecs et limitations
|
||||||
|
|
||||||
|
### 4.1 NPU Talker (ONNX Runtime QNN EP)
|
||||||
|
- **Quantification par defaut (int8/int16)** : le talker diverge apres ~10 steps, produit du bruit
|
||||||
|
- **Options fp16** (`htp_precision`, `enable_htp_fp16_precision`) : aucun effet observable, probablement ignorees par le HTP backend
|
||||||
|
- **Resultat** : EOS premature (1.4-2.2s au lieu de 4s) ou degeneration
|
||||||
|
- **Cause** : la quantification automatique de ONNX Runtime QNN EP est trop agressive pour un modele autoregistratif
|
||||||
|
|
||||||
|
### 4.2 NPU CP (ONNX Runtime QNN EP)
|
||||||
|
- Meme probleme que le talker : les codebooks secondaires sont corrompus
|
||||||
|
- Cause une pause audible entre les mots (les embeddings de codebooks sont faux)
|
||||||
|
- Le modele ne converge pas vers EOS (185 tokens sans arret)
|
||||||
|
|
||||||
|
### 4.3 NPU CP (ExecuTorch fp16)
|
||||||
|
- Le runner standalone produit des codes en 55ms → rapide
|
||||||
|
- Mais les codes sont **completement differents** du CPU (0/15 match)
|
||||||
|
- L'audio genere est du bruit
|
||||||
|
- **Cause** : le fp16 change suffisamment les logits pour que l'argmax donne des codebooks differents, et l'autoregression amplifie
|
||||||
|
|
||||||
|
### 4.4 CP KV-cache avec buffer fixe
|
||||||
|
- Approche : KV padding a 16 positions, shift (drop oldest) a chaque step
|
||||||
|
- Fonctionne sur PC (valide 15/15 vs PyTorch)
|
||||||
|
- Sur tablette : degeneration au step 53+ (token 1894 x10)
|
||||||
|
- **Cause** : apres 16 steps, la position 0 (hidden state du talker) est perdue du cache → le modele perd le contexte initial
|
||||||
|
- **Solution adoptee** : revenir au CP fullseq (re-run la sequence complete a chaque step)
|
||||||
|
|
||||||
|
### 4.5 Subprocess NPU via su
|
||||||
|
- Le NPU (Hexagon DSP) necessite root (`su`) pour l'acces
|
||||||
|
- `su -c 'command'` ne transmet pas stdin/stdout au process enfant dans Java
|
||||||
|
- Named pipes (FIFO) causent un deadlock (blocking open bidirectionnel)
|
||||||
|
- **Solution** : JNI natif (elimine le besoin de subprocess)
|
||||||
|
|
||||||
|
### 4.6 Sampling vs Greedy
|
||||||
|
- **Greedy** : le modele ne genere JAMAIS EOS (gap logit de -19 a -28 entre EOS et top codec)
|
||||||
|
- **Sampling** : produit des resultats variables, mais converge vers EOS grace a la stochasticite
|

|
- La repetition penalty (1.05x par token unique) n'est pas suffisante seule pour pousser vers EOS
|
||||||
|
- C'est le sampling + tts_pad qui permet l'EOS naturel

## 6. Fichiers cles
|
||||||
|
|
||||||
|
### Sur le PC (/opt/Kazeia/)
|
||||||
|
- `models_qnn/qwen3-tts-onnx/` — tous les ONNX exports
|
||||||
|
- `models_qnn/cp_kv_fp16.pte` — CP ExecuTorch NPU (pret mais qualite insuffisante)
|
||||||
|
- `models_qnn/cp_data/` — embeddings + rotary pour le runner
|
||||||
|
- `executorch/build-android/` — libs compilees + cp_runner
|
||||||
|
- `executorch/examples/qualcomm/executor_runner/cp_runner.cpp` — source du runner
|
||||||
|
|
||||||
|
### Sur la tablette (/data/local/tmp/kazeia/)
|
||||||
|
- `models/qwen3-tts-npu/` — modeles ONNX + embeddings + codebooks
|
||||||
|
- `models/cp_kv_fp16.pte` — CP ExecuTorch
|
||||||
|
- `cp_runner` — binaire runner C++ (ARM64)
|
||||||
|
- `cp_data/` — donnees statiques pour le runner
|
||||||
|
|
||||||
|
### Dans l'app (kazeia-android/)
|
||||||
|
- `app/src/main/java/com/kazeia/tts/Qwen3TtsEngine.kt` — moteur TTS complet
|
||||||
|
- `app/src/main/jniLibs/arm64-v8a/libexecutorch.so` — JNI ExecuTorch (49MB)
|
||||||
|
- `app/src/main/jniLibs/arm64-v8a/libfbjni.so` — dependance JNI
|
||||||
|
- `app/src/main/jniLibs/arm64-v8a/libqnn_executorch_backend.so` — backend QNN
|
||||||
|
- `app/libs/executorch.jar` — classes Java ExecuTorch
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 7. Pistes d'optimisation (non explorees)
|
||||||
|
|
||||||
|
1. **Quantification calibree** (use_16a8w avec donnees de calibration) — pourrait preserver la qualite sur NPU
|
||||||
|
2. **Export talker en .pte fp32** — ExecuTorch CPU pourrait etre plus rapide que ONNX Runtime
|
||||||
|
3. **Streaming decode** — decoder le premier chunk pendant la generation du deuxieme
|
||||||
|
4. **NNAPI EP** — backend GPU Adreno (pas HTP) pour le talker/CP
|
||||||
|
5. **Modele TTS plus petit** — SpeechT5 ou VITS pour un RTF < 1 au detriment de la qualite
|
||||||
|
6. **KV-cache CP correct** — augmenter CP_KV_LEN a 17 (au lieu de 16) pour ne pas perdre la position 0
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 8. Lecons apprises
|
||||||
|
|
||||||
|
1. **Les modeles TTS sont beaucoup plus sensibles a la precision que les LLM** — le LLM Qwen3 tourne a 90 tok/s en int4 sur NPU, mais le TTS ne supporte meme pas le fp16
|
||||||
|
2. **L'autoregression amplifie les erreurs** — une petite erreur au step N se propage et s'amplifie aux steps N+1, N+2...
|
||||||
|
3. **Le debug embedding-level est essentiel** — sans comparer tensor par tensor avec PyTorch, impossible de trouver les bugs (tts_pad, q_norm/k_norm)
|
||||||
|
4. **ONNX Runtime QNN EP != ExecuTorch QNN** — deux stacks completement differentes avec des comportements de quantification differents
|
||||||
|
5. **Le `su` Android est un cauchemar pour l'IPC** — stdin/stdout ne passent pas, il faut du JNI natif ou des fichiers

|
**Encoder** (HfWhisperEncoder) :
|
||||||
|
- Input : `input_features` [1, 80, 3000] fp16
|
||||||
|
- Output : Cross-attention KV caches (N layers × k,v)

|
||||||
|
|
||||||
|
**Decoder** (HfWhisperDecoder) — KV-cache autorégressif :
|
||||||
|
- Inputs :
|
||||||
|
- `input_ids` : [1, 1] int32 (un token à la fois)
|
||||||
|
- `attention_mask` : [1, 1, 1, 200] fp16 (right-aligned, -100 pour masqué)
|
||||||

|
||||||
|
- `k_cache_cross_N` / `v_cache_cross_N` : Cross KV caches (depuis encoder)
|
||||||
|
- `position_ids` : [1] int32
|
||||||
|

|
||||||
|
|
||||||
|
## Déploiement sur tablette
|
||||||
|
|
||||||
|
### 1. Copier les modèles
|
||||||
|
```bash
|
||||||
|
MODEL_DIR="/data/local/tmp/kazeia/models/whisper-small-sm8750"
|
||||||
|
SRC="<chemin_local>/whisper_small-precompiled_qnn_onnx-float-qualcomm_snapdragon_8_elite"
|
||||||
|
|
||||||
|
adb shell "mkdir -p $MODEL_DIR"
|
||||||
|
adb push $SRC/HfWhisperEncoder.onnx $MODEL_DIR/
|
||||||
|
adb push $SRC/HfWhisperEncoder_qairt_context.bin $MODEL_DIR/
|
||||||
|
adb push $SRC/HfWhisperDecoder.onnx $MODEL_DIR/
|
||||||
|
adb push $SRC/HfWhisperDecoder_qairt_context.bin $MODEL_DIR/
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Copier les assets partagés
|
||||||
|
Les fichiers `mel_filters.json` et `vocab.json` sont communs à toutes les variantes Whisper :
|
||||||
|
```bash
|
||||||
|
# Si déjà présents depuis une autre variante :
|
||||||
|
adb shell "cp /data/local/tmp/kazeia/models/whisper-sm8750/mel_filters.json $MODEL_DIR/"
|
||||||
|
adb shell "cp /data/local/tmp/kazeia/models/whisper-sm8750/vocab.json $MODEL_DIR/"
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Configurer le chemin dans KazeiaService.kt
|
||||||
|
```kotlin
|
||||||
|
npuStt.load("$modelsDir/whisper-small-sm8750")
|
||||||
|
```
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## Dépannage
|
||||||
|
|
||||||
|
### "resource failed to call close"
|
||||||
|
Warnings bénins de l'ONNX Runtime. Les sessions ORT non fermées proprement génèrent ces messages lors du GC.
|
||||||
|
|
||||||
|
### Modèle ne se charge pas
|
||||||
|
- Vérifier que `HfWhisperEncoder_qairt_context.bin` est dans le MÊME répertoire que `HfWhisperEncoder.onnx`
|
||||||
|
- Vérifier que `libQnnHtp.so` est accessible via `nativeLibDir`
|
||||||
|
- Le modèle doit être compilé pour le bon chipset (sm8750, pas sm8750-ac ni sm8850)
|
||||||
|
|
||||||
|
### Mauvaise détection de langue
|
||||||
|
Whisper-Base est peu fiable pour la détection de langue sur segments courts. Whisper-Small est nettement meilleur. Si besoin, on peut forcer le token de langue après SOT.

## 3. Problèmes rencontrés
|
||||||
|
|
||||||
|
### 3.1 Chatterbox — Opérateurs ONNX non standard
|
||||||
|
|
||||||
|
**Problème central** : Les modèles ONNX de Chatterbox utilisent des **opérateurs Microsoft custom** qui ne sont supportés ni par QNN (Qualcomm) ni par AI Hub :
|
||||||
|
|
||||||
|
| Opérateur | Domaine | Utilisations | Problème |
|
||||||
|
|-----------|---------|-------------|----------|
|
||||||
|
| `GroupQueryAttention` | `com.microsoft` | 30 (1 par couche) | Non supporté par QNN/AI Hub |
|
||||||
|
| `SkipSimplifiedLayerNormalization` | `com.microsoft` | 60 | Non supporté par QNN/AI Hub |
|
||||||
|
| `SimplifiedLayerNormalization` | ONNX opset 21 | 1 | Non supporté par QNN (opset trop récent) |
|
||||||
|
|
||||||
|
Ces opérateurs sont des **optimisations internes d'ONNX Runtime** (fusion GQA, skip-connection + layernorm fusionnés). Ils fonctionnent sur CPU via ORT mais ne peuvent pas être compilés pour le NPU Qualcomm.
|
||||||
|
|
||||||
|
**Conséquence** : Le language model (30 couches, ~85% du temps de calcul) tourne entièrement sur **CPU** à ~1 tok/s sur la tablette. Sur PC, il tourne à ~45 tok/s (CPU x86 plus puissant).
|
||||||
|
|
||||||
|
**Tentatives de résolution** :
|
||||||
|
1. ✅ Compilation AI Hub avec opset 21 → Échec (`SimplifiedLayerNormalization` non supporté)
|
||||||
|
2. ✅ Patch opset 21→17 + remplacement LayerNorm → Échec (`int64` non supporté)
|
||||||
|
3. ✅ Ajout `--truncate_64bit_io` → Échec (`GroupQueryAttention` non supporté)
|
||||||
|
4. ❌ Le modèle FP32 utilise aussi `GroupQueryAttention`
|
||||||
|
5. ❌ Le modèle Q4F16 utilise aussi `GroupQueryAttention`
|
||||||
|
|
||||||
|
**Solution potentielle** : Retrouver le modèle PyTorch original de Chatterbox et le ré-exporter en ONNX avec des opérateurs standard (attention multi-head classique au lieu de GQA fusionné). Le modèle source est sur HuggingFace (`resemble-ai/chatterbox-multilingual`) mais l'export ONNX standard n'a pas été publié.
|
||||||
|
|
||||||
|
**Autre problème constaté** : La variante Q4F16 (quantifiée INT4) produit de l'audio de **mauvaise qualité** sur la tablette — le son "ne correspond à rien" selon le test utilisateur. Sur PC, le même modèle Q4F16 fonctionne correctement (63 tokens, stop token atteint, 2.5s d'audio). La différence pourrait venir de la précision des opérations INT4 sur ARM vs x86.
|
||||||
|
|
||||||
|
### 3.2 Qwen3-TTS — Speech Decoder non exportable
|
||||||
|
|
||||||
|
**Problème central** : Le pipeline Qwen3-TTS est composé de 4 modules dont **seuls 2 sont exportables** :
|
||||||
|
|
||||||
|
| Module | Export ONNX | Export ExecuTorch | Bloqueur |
|
||||||
|
|--------|------------|-------------------|----------|
|
||||||
|
| **Speaker Encoder** (8.9M) | ⚠️ Non testé (probablement OK) | Non tenté | Conv1D simple |
|
||||||
|
| **Talker LM** (754M) | ❌ Échoue | ✅ **Fonctionne** (90.7 tok/s NPU) | — |
|
||||||
|
| **Code Predictor** (141M) | ✅ **Exporté** (440 MB) | Non tenté | — |
|
||||||
|
| **Speech Decoder** (114M) | ❌ **Échoue** | ❌ Échoue | `SplitResidualVectorQuantizer` + `SnakeBeta` |
|
||||||
|
|
||||||
|
Le **Speech Decoder** est le bloqueur. Il contient :
|
||||||
|
|
||||||
|
1. **`SplitResidualVectorQuantizer`** : Utilise `torch.autograd.Function` avec `vmap` — une fonctionnalité PyTorch avancée incompatible avec tout export (ONNX legacy, dynamo, jit.trace). C'est le composant qui convertit les indices de codebook en vecteurs continus.
|
||||||
|
|
||||||
|
2. **`SnakeBeta`** activation : Bien que son `forward()` soit du PyTorch standard (`x + sin²(αx)/β`), elle est utilisée dans des blocs qui contiennent aussi le VQ, rendant l'export impossible pour l'ensemble.
|
||||||
|
|
||||||
|
**Tentatives de résolution** :
|
||||||
|
1. ✅ Export ONNX legacy (`torch.onnx.export`) → `RuntimeError: unordered_map::at` (vmap)
|
||||||
|
2. ✅ Export dynamo (`torch.onnx.export(dynamo=True)`) → Échec (strict et non-strict)
|
||||||
|
3. ✅ Export TorchScript (`torch.jit.trace`) → `RuntimeError: unordered_map::at`
|
||||||
|
4. ✅ Décomposition en sous-modules (pre_conv, pre_transformer, conv_decoder) → Le VQ bloque toujours
|
||||||
|
5. ✅ Export du code predictor seul → Réussi (mais inutile sans le speech decoder)
|
||||||
|
|
||||||
|
**Solution potentielle** : Réécrire le `SplitResidualVectorQuantizer.decode()` en opérations PyTorch basiques (embedding lookups + Conv1d projections) sans utiliser `torch.autograd.Function` ni `vmap`. Les poids des codebooks ont été extraits en numpy. Cela demande de comprendre précisément le flow de données du VQ decode.

## 5. Chemins de résolution
|
||||||
|
|
||||||
|
### Option A : Ré-exporter Chatterbox depuis PyTorch (recommandé)
|
||||||
|
|
||||||
|
**Principe** : Charger le modèle PyTorch original (`resemble-ai/chatterbox-multilingual`), désactiver les optimisations ORT, et exporter en ONNX standard.
|
||||||
|
|
||||||
|
**Avantages** :
|
||||||
|
- Le pipeline complet est déjà implémenté dans l'app Android (`ChatterboxTtsEngine.kt`)
|
||||||
|
- Speech encoder, embed tokens, et conditional decoder tournent déjà sur CPU (petits, rapides)
|
||||||
|
- Seul le language model a besoin du NPU
|
||||||
|
|
||||||
|
**Étapes** :
|
||||||
|
1. Charger `resemble-ai/chatterbox-multilingual` en PyTorch
|
||||||
|
2. Exporter le language model en ONNX opset 17 avec attention standard (pas GQA fusionné)
|
||||||
|
3. Compiler via AI Hub pour SM8750
|
||||||
|
4. Remplacer le `language_model_q4f16.onnx` par la version QNN precompiled
|
||||||
|
5. Les 3 autres modèles restent en ONNX CPU
|
||||||
|
|
||||||
|
**Risques** : Le modèle PyTorch original pourrait ne pas être public ou avoir une architecture différente des ONNX publiés.
|
||||||
|
|
||||||
|
**Estimation** : 2-4h de travail si le modèle PyTorch est accessible.
|
||||||
|
|
||||||
|
### Option B : Réécrire le VQ decode de Qwen3-TTS
|
||||||
|
|
||||||
|
**Principe** : Remplacer le `SplitResidualVectorQuantizer` par des opérations ONNX-compatibles (embedding lookups).
|
||||||
|
|
||||||
|
**Avantages** :
|
||||||
|
- Le Talker tourne déjà à 90 tok/s sur NPU
|
||||||
|
- Le Code Predictor est déjà exporté en ONNX
|
||||||
|
- Qualité TTS supérieure (Qwen3 est plus récent)
|
||||||
|
|
||||||
|
**Étapes** :
|
||||||
|
1. Analyser le flow de `quantizer.decode()` (codebook lookup + projection + sommation)
|
||||||
|
2. Réimplémenter en PyTorch sans `vmap` ni `autograd.Function`
|
||||||
|
3. Exporter le speech decoder complet en ONNX
|
||||||
|
4. Intégrer dans l'app Android
|
||||||
|
|
||||||
|
**Risques** : La réimplémentation du VQ pourrait introduire des différences numériques affectant la qualité audio.
|
||||||
|
|
||||||
|
**Estimation** : 4-8h de travail.
|
||||||
|
|
||||||
|
### Option C : Chatterbox CPU avec optimisations
|
||||||
|
|
||||||
|
**Principe** : Garder Chatterbox sur CPU mais optimiser :
|
||||||
|
- Utiliser NNAPI EP au lieu de CPU pur (délègue certaines ops au DSP)
|
||||||
|
- Réduire le nombre de tokens max (limiter à ~50 tokens au lieu de 512)
|
||||||
|
- Pré-encoder les voix au premier lancement (éviter le coût du speech encoder)
|
||||||
|
|
||||||
|
**Avantages** : Pas de recompilation nécessaire, fonctionne maintenant.
|
||||||
|
|
||||||
|
**Inconvénients** : Toujours lent (~1-5 tok/s), latence de 10-30s par phrase.
|
||||||
|
|
||||||
|
### Option D : TTS léger (Piper) comme solution intermédiaire
|
||||||
|
|
||||||
|
**Principe** : Utiliser Piper TTS (VITS, ~30 MB) pour avoir du TTS français fonctionnel immédiatement, en parallèle du travail sur Chatterbox/Qwen3-TTS NPU.
|
||||||
|
|
||||||
|
**Avantages** :
|
||||||
|
- Modèles ONNX standard, très légers
|
||||||
|
- Latence ~100ms
|
||||||
|
- Français disponible
|
||||||
|
- Pas de compilation NPU nécessaire
|
||||||
|
|
||||||
|
**Inconvénients** :
|
||||||
|
- Pas de voice cloning
|
||||||
|
- Qualité inférieure (voix synthétique)
|
||||||
|
- Une seule voix par modèle
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 6. Recommandation
|
||||||
|
|
||||||
|
**Court terme** : Option A (ré-export Chatterbox PyTorch) est la voie la plus prometteuse. Le pipeline Android est déjà prêt, seul le language model a besoin du NPU. Si le modèle PyTorch est accessible, c'est réalisable rapidement.
|
||||||
|
|
||||||
|
**Moyen terme** : Option B (Qwen3-TTS VQ rewrite) donnerait les meilleures performances (Talker déjà à 90 tok/s NPU) mais demande plus de travail d'ingénierie.
|
||||||
|
|
||||||
|
**Fallback** : Option D (Piper) comme TTS temporaire pendant le développement NPU.

# Tests Qwen3-TTS sur OnePlus Pad 3 — Journal
|
||||||
|
|
||||||
|
**Date** : 29 mars 2026
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Environnement
|
||||||
|
|
||||||
|
- **Tablette** : OnePlus Pad 3 (Snapdragon 8 Elite, 16 GB RAM)
|
||||||
|
- **Runtime** : Termux + Python 3.12 + PyTorch 2.9.0 (Termux native ARM)
|
||||||
|
- **Modèle** : Qwen3-TTS-12Hz-0.6B-Base (local, `/data/local/tmp/kazeia/models/qwen3-tts/`)
|
||||||
|
- **Dépendances** : transformers 4.57.3, torchaudio 2.9.0, soundfile, einops
|
||||||
|
- **Mocks** : librosa (soundfile+scipy), soxr (scipy), sox, onnxruntime
|
||||||
|
|
||||||
|
## Résultats des tests
|
||||||
|
|
||||||
|
### Test 1 : float32 complet
|
||||||
|
- **Résultat** : OOM (killed) — le modèle 1.7 GB + speech tokenizer 651 MB + overhead dépassent la RAM disponible
|
||||||
|
- **RAM utilisée** : >10 GB avant crash
|
||||||
|
|
||||||
|
### Test 2 : float16
|
||||||
|
- **Résultat** : NaN dans le code predictor (`RuntimeError: probability tensor contains either inf, nan or element < 0`)
|
||||||
|
- **Cause** : float16 n'a pas assez de précision pour le softmax du code predictor (5 couches)
|
||||||
|
|
||||||
|
### Test 3 : float16 + code predictor float32
|
||||||
|
- **Résultat** : dtype mismatch (`RuntimeError: expected m1 and m2 to have the same dtype, but got: float != c10::Half`)
|
||||||
|
- **Cause** : le code predictor en float32 reçoit des tenseurs float16 du talker — les types ne sont pas automatiquement castés dans le forward couplé
|
||||||
|
|
||||||
|
### Test 4 : bfloat16 ✅
|
||||||
|
- **Résultat** : **Fonctionne**
|
||||||
|
- **"Bonjour."** : 39.5s pour 1.0s d'audio (RTF 39.5x)
|
||||||
|
- **"Bonjour, je suis là pour vous écouter."** : 109.4s pour 2.6s d'audio (RTF 41.5x)
|
||||||
|
- **Explication** : bfloat16 a le même range que float32 (8 bits d'exposant) mais moins de mantisse. Le code predictor ne produit plus de NaN.
|
||||||
|
- **RAM** : ~3.8 GB (modèle) + ~1-2 GB (inference) = ~5-6 GB total
|
||||||
|
|
||||||
|
### Test 5 : INT8 dynamic quantization
|
||||||
|
- **Résultat** : Échec (`NoQEngine` — le backend quantization n'est pas compilé dans la version Termux de PyTorch)
|
||||||
|
|
||||||
|
### Test 6 : torch.compile
|
||||||
|
- **Résultat** : OOM — l'overhead de compilation consomme trop de RAM
|
||||||
|
|
||||||
|
### Test 7 : Speaker encoder timing
|
||||||
|
- **Sur PC** : 2-10s selon la voix
|
||||||
|
- **Sur tablette CPU** : **688s (11 min)** — inutilisable
|
||||||
|
- **Solution** : Pré-calculer les embeddings sur PC, les stocker en .npy (4 KB chacun), les charger instantanément
|
||||||
|
|
||||||
|
## Architecture validée
|
||||||
|
|
||||||
|
```
|
||||||
|
[PC - pré-calcul]
|
||||||
|
Voix WAV → Speaker Encoder → embedding .npy (1024 floats, 4 KB)
|
||||||
|
|
||||||
|
[Tablette - runtime]
|
||||||
|
embedding .npy (instantané)
|
||||||
|
+ texte
|
||||||
|
↓
|
||||||
|
Talker LM (28 couches, bfloat16 CPU) → speech tokens
|
||||||
|
↓
|
||||||
|
Code Predictor (5 couches, bfloat16) → 15 codebooks
|
||||||
|
↓
|
||||||
|
Speech Decoder (Transformer + VQ + ConvNet) → audio WAV
|
||||||
|
```
|
||||||
|
|
||||||
|
## Performances actuelles (CPU bfloat16, 6 threads)
|
||||||
|
|
||||||
|
| Phrase | Tokens | Temps | Audio | RTF |
|
||||||
|
|--------|--------|-------|-------|-----|
|
||||||
|
| "Bonjour." | ~20 | 39.5s | 1.0s | 39.5x |
|
||||||
|
| "Bonjour, je suis là..." | ~50 | 109.4s | 2.6s | 41.5x |
|
||||||
|
|
||||||
|
**Goulot d'étranglement** : Le talker (28 couches transformer autorégressif) représente ~90% du temps.
|
||||||
|
|
||||||
|
## Estimation avec NPU
|
||||||
|
|
||||||
|
Le talker .pte a été testé à **90.7 tok/s** sur le NPU Hexagon (rapport précédent).
|
||||||
|
Sur CPU bfloat16, le talker fait ~0.5 tok/s (estimé d'après les temps).
|
||||||
|
|
||||||
|
| Composant | CPU actuel | NPU estimé |
|
||||||
|
|-----------|-----------|------------|
|
||||||
|
| Talker (50 tokens) | ~100s | **~0.6s** |
|
||||||
|
| Code predictor | ~3s | ~3s (CPU) |
|
||||||
|
| Speech decoder | ~6s | ~6s (CPU) |
|
||||||
|
| **Total** | **~109s** | **~10s** |
|
||||||
|
|
||||||
|
## Blocages pour l'intégration NPU
|
||||||
|
|
||||||
|
1. **`qnn_llama_runner` incompatible** : Le runner prend du texte brut et utilise un TEXT tokenizer. Le talker TTS attend des embeddings texte pré-calculés (via `text_projection`) + un speaker embedding. Les entrées/sorties ne correspondent pas.
|
||||||
|
|
||||||
|
2. **ExecuTorch Python pas dispo sur Termux** : Le package pip `executorch` n'a pas de wheel ARM. La compilation locale nécessiterait le NDK + CMake cross-compilation.
|
||||||
|
|
||||||
|
3. **Couplage talker ↔ code predictor** : Le code predictor est appelé à CHAQUE step du talker (pas après). Ses sorties (15 codebooks) sont ré-injectées dans le talker comme embeddings pour le step suivant.
|
||||||
|
|
||||||
|
## Solutions en cours d'exploration
|
||||||
|
|
||||||
|
### A. Service TTS résident (CPU bfloat16)
|
||||||
|
Script Python (`tts_service.py`) qui reste en mémoire avec le modèle chargé. L'app Android écrit une requête JSON, le service génère le WAV.
|
||||||
|
- **Avantage** : Fonctionne maintenant (validé)
|
||||||
|
- **Inconvénient** : ~40-110s par phrase (inutilisable en production)
|
||||||
|
|
||||||
|
### B. Compiler ExecuTorch Python pour Termux/ARM
|
||||||
|
Cross-compiler le binding Python ExecuTorch pour aarch64-android. Permettrait de charger le `.pte` et faire les forward passes sur NPU directement depuis Python.
|
||||||
|
- **Avantage** : Garderait le couplage talker ↔ code predictor
|
||||||
|
- **Difficulté** : Compilation cross-platform complexe
|
||||||
|
|
||||||
|
### C. Runner C++ custom pour le talker TTS
|
||||||
|
Modifier `qnn_llama_runner` pour accepter des embeddings pré-calculés au lieu de texte, et sortir des token IDs bruts.
|
||||||
|
- **Avantage** : Réutilise l'infra ExecuTorch existante
|
||||||
|
- **Difficulté** : Modification C++ du runner
|
||||||
|
|
||||||
|
### D. Pipeline découplé (talker NPU → code predictor CPU)
|
||||||
|
Accepter une qualité légèrement réduite en découplant : le talker NPU génère codebook 0, puis le code predictor génère codebooks 1-14 en un seul pass (pas step-by-step).
|
||||||
|
- **Avantage** : Plus simple à implémenter
|
||||||
|
- **Inconvénient** : Qualité potentiellement dégradée
|
||||||

# Gradle start up script for POSIX generated by Gradle.
|
||||||
|
#
|
||||||
|
# Important for running:
|
||||||
|
#
|
||||||
|
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
|
||||||
|
# noncompliant, but you have some other compliant shell such as ksh or
|
||||||
|
# bash, then to run this script, type that shell name before the whole
|
||||||
|
# command line, like:
|
||||||
|
#
|
||||||
|
# ksh Gradle
|
||||||
|
#
|
||||||
|
# Busybox and similar reduced shells will NOT work, because this script
|
||||||
|
# requires all of these POSIX shell features:
|
||||||
|
# * functions;
|
||||||
|
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
|
||||||
|
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
|
||||||
|
# * compound commands having a testable exit status, especially «case»;
|
||||||
|
# * various built-in commands including «command», «set», and «ulimit».
|
||||||
|
#
|
||||||
|
# Important for patching:
|
||||||
|
#
|
||||||
|
# (2) This script targets any POSIX shell, so it avoids extensions provided
|
||||||
|
# by Bash, Ksh, etc; in particular arrays are avoided.
|
||||||
|
#
|
||||||
|
# The "traditional" practice of packing multiple parameters into a
|
||||||
|
# space-separated string is a well documented source of bugs and security
|
||||||
|
# problems, so this is (mostly) avoided, by progressively accumulating
|
||||||
|
# options in "$@", and eventually passing that to Java.
|
||||||
|
#
|
||||||
|
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
|
||||||
|
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
|
||||||
|
# see the in-line comments for details.
|
||||||
|
#
|
||||||
|
# There are tweaks for specific operating systems such as AIX, CygWin,
|
||||||
|
# Darwin, MinGW, and NonStop.
|
||||||
|
#
|
||||||
|
# (3) This script is generated from the Groovy template
|
||||||
|
# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt

|
||||||
|
|
||||||
|
## Principe
|
||||||
|
|
||||||
|
Chaque composant (LLM, STT, TTS, VAD) est une interface Kotlin.
|
||||||
|
L'implémentation concrète est injectée au démarrage.
|
||||||
|
Changer de LLM = écrire une nouvelle classe qui implémente l'interface, rien d'autre ne bouge.

## Notes pour la session Claude Code
|
||||||
|
|
||||||
|
### Modèles à déployer sur la tablette
|
||||||
|
|
||||||
|
Les modèles ne sont PAS dans l'APK. Ils sont poussés via ADB :
|
||||||
|
```bash
|
||||||
|
adb push qwen3-4b-genie/ /data/local/tmp/kazeia/models/qwen3-4b/
|
||||||
|
adb push whisper-qualcomm/ /data/local/tmp/kazeia/models/whisper/
|
||||||
|
adb push chatterbox/ /data/local/tmp/kazeia/models/chatterbox/
|
||||||
|
```
|
||||||
|
|
||||||
|
L'application au démarrage vérifie la présence des modèles et affiche une erreur si manquants.
|
||||||
|
|
||||||
|
### Ordre d'implémentation recommandé
|
||||||
|
|
||||||
|
1. **Interface chat basique** (Activity + RecyclerView) — sans IA, juste l'UI
|
||||||
|
2. **LLM texte seul** (taper un message → Genie répond → affichage)
|
||||||
|
3. **VAD + micro** (AudioRecord + Silero → détection parole)
|
||||||
|
4. **STT** (Whisper → transcription affichée)
|
||||||
|
5. **TTS** (réponse LLM → Chatterbox → audio)
|
||||||
|
6. **Pipeline complet** (VAD → STT → LLM → TTS, sans bouton)
|
||||||
|
|
||||||
|
### Swap de LLM
|
||||||
|
|
||||||
|
Pour changer de LLM, il suffit de modifier UNE ligne dans KazeiaService.kt :
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
// Option A : Genie SDK (NPU, Qwen3-4B pré-compilé)
|
||||||
|
llm = GenieLlmEngine()
|
||||||
|
|
||||||
|
// Option B : ExecuTorch (NPU, modèle custom .pte)
|
||||||
|
llm = ExecuTorchLlmEngine()
|
||||||
|
|
||||||
|
// Option C : llama.cpp (CPU, n'importe quel GGUF)
|
||||||
|
llm = LlamaCppLlmEngine()
|
||||||
|
```
|
||||||
|
|
||||||
|
Toutes les implémentations respectent la même interface LlmEngine.
|
||||||
|
Le reste de l'application ne change pas.
|
||||||
