#### setting up STT/TTS services
For speech-to-text (STT) and text-to-speech (TTS) functionality:
1. The project uses Whisper.cpp for STT and Kokoro for TTS
2. Docker Compose automatically downloads the required Whisper model on first run
3. To start all services: `make docker-up`
4. To start only STT service: `make docker-up-whisper`
5. To start only TTS service: `make docker-up-kokoro`
6. To stop all services: `make docker-down`
7. To stop only STT service: `make docker-down-whisper`
8. To stop only TTS service: `make docker-down-kokoro`
9. To view all service logs: `make docker-logs`
10. To view only STT service logs: `make docker-logs-whisper`
11. To view only TTS service logs: `make docker-logs-kokoro`
12. The STT service runs on http://localhost:8081
13. The TTS service runs on http://localhost:8880
