| - Uses **faster-whisper** (tiny) for ASR | |
| ### Environment variables (set in Space → Settings → Secrets) | |
| - `BACKEND_LLM=openai` (or `groq`) | |
| - If `openai`: `OPENAI_API_KEY=<your-key>` | |
| - If `groq`: `GROQ_API_KEY=<your-key>` | |
| - `TTS_ENGINE=piper` | |
| - `PIPER_MODEL=models/piper/en_US-amy-medium.onnx` | |
