+# voice-generator
+
+Generate a short script with an **LLM** (ChatGPT or Claude), then turn it into speech with a
+**Text-to-Speech (TTS)** engine. Two TTS providers are supported and interchangeable at request time:
+
+| Provider     | `tts` value   | Auth header                  | Response          | Notes                                   |
+|--------------|---------------|------------------------------|-------------------|-----------------------------------------|
+| ElevenLabs   | `elevenlabs`  | `xi-api-key: <key>`          | streamed MP3      | Default. `eleven_multilingual_v2` model |
+| 60dB         | `60db`        | `Authorization: Bearer <key>`| JSON (base64 MP3) | `/tts-synthesize`, decoded to disk      |
+
+---
+
+## 🧩 Architecture
+
+```
+Angular frontend ──POST /api/llm/:type/:llm──► LLM service ──► storage/data/<name>-<llm>.json
+   │                                                                     │
+   └────POST /api/voice/:llm?tts=<provider>──► voice route ──reads JSON──┘
+                                  │
+                                  ▼
+                 ElevenLabs OR 60dB adapter ──► storage/voices/<name>-<llm>.mp3
+                                                        │
+   ◄──── { success, data: <public MP3 url> } ──────────┘   (served from /storage)
+```
+
+The voice route does **not** receive the text directly — it reads the script JSON produced by the
+LLM step, then hands the text to the selected TTS adapter.
+
+---
+
+## 🔗 API
+
+| Method | Endpoint                              | Description                                            |
+|--------|---------------------------------------|--------------------------------------------------------|
+| POST   | `/api/llm/:type/:llm`                 | Generate a script (`type` = `biography`/`summary`)     |
+| POST   | `/api/voice/:llm?tts=<provider>`      | Synthesize the script to MP3. `tts` defaults to `elevenlabs` |
+| GET    | `/api/voice/health/tts`               | ElevenLabs connectivity/key check                      |
+
+**Voice request example**
+
+```bash
+# ElevenLabs (default — ?tts can be omitted)
+curl -X POST "http://localhost:3000/api/voice/chatgpt" \
+  -H "Content-Type: application/json" -d '{"name":"Ridley Scott"}'
+
+# 60dB
+curl -X POST "http://localhost:3000/api/voice/chatgpt?tts=60db" \
+  -H "Content-Type: application/json" -d '{"name":"Ridley Scott"}'
+```
+
+Provider selection lives in `backend-javascript/src/routes/voice.routes.js` (`getTtsProvider()`),
+mirroring the LLM `getProvider()` pattern. Each adapter exposes the same
+`generateVoice(text, voiceId, outputPath)` signature:
+
+- `src/services/voice/voice.service.js` — ElevenLabs
+- `src/services/voice/sixtydb.service.js` — 60dB
+
+---
+
+## 🛠 Configuration
+
+`backend-javascript/.env` (see `.env.template`):
+
+```env
+# true => local mocks, no API calls | false => real provider APIs
+USE_MOCK=true
+
+# ElevenLabs
+ELEVENLABS_API_KEY=eleven-your-key
+ELEVENLABS_VOICE_ID=eleven-voice-id-xxxxxxxx
+
+# 60dB (VOICE_ID optional — blank uses the 60dB system default voice)
+SIXTYDB_API_KEY=sixtydb-your-key
+SIXTYDB_VOICE_ID=
+```
+
+When `USE_MOCK=true`, the backend copies a pre-recorded sample instead of calling any provider, so
+no API key is needed to demo the flow.
+
+---
+
+## 🎚 Frontend
+
+In the Angular UI a **Voix (TTS)** dropdown selects the provider (`ElevenLabs` / `60dB`). The choice
+is sent through as `?tts=` and the voice buttons / status messages relabel to the active provider.
+
+> Note: in mock mode the bundled sample audio is ElevenLabs-style; switching to 60dB relabels the UI
+> but plays the same sample. Real synthesis (`USE_MOCK=false`) uses the selected provider end to end.
+
+---
+
+## ⚙️ Quick start
+
+```bash
+# Backend
+cd backend-javascript
+npm install
+npm start            # http://localhost:3000
+
+# Frontend
+cd frontend-angular
+npm install
+npm start            # http://localhost:4200
