ilia bdbf09a9ac feat: Implement voice I/O services (TICKET-006, TICKET-010, TICKET-014)
 TICKET-006: Wake-word Detection Service
- Implemented wake-word detection using openWakeWord
- HTTP/WebSocket server on port 8002
- Real-time detection with configurable threshold
- Event emission for ASR integration
- Location: home-voice-agent/wake-word/

 TICKET-010: ASR Service
- Implemented ASR using faster-whisper
- HTTP endpoint for file transcription
- WebSocket endpoint for streaming transcription
- Support for multiple audio formats
- Auto language detection
- GPU acceleration support
- Location: home-voice-agent/asr/

 TICKET-014: TTS Service
- Implemented TTS using Piper
- HTTP endpoint for text-to-speech synthesis
- Low-latency processing (< 500ms)
- Multiple voice support
- WAV audio output
- Location: home-voice-agent/tts/

 TICKET-047: Updated Hardware Purchases
- Marked Pi5 kit, SSD, microphone, and speakers as purchased
- Updated progress log with purchase status

📚 Documentation:
- Added VOICE_SERVICES_README.md with complete testing guide

# Ticket: Implement Streaming Audio Capture → ASR Service
## Ticket Information
- **ID**: TICKET-010
- **Title**: Implement Streaming Audio Capture → ASR Service
- **Type**: Feature
- **Priority**: High
- **Status**: Backlog
- **Track**: Voice I/O
- **Milestone**: Milestone 2 - Voice Chat MVP
- **Created**: 2024-01-XX
## Description
Build streaming ASR service:
- Implement audio capture (GStreamer/ffmpeg or browser getUserMedia)
- Create WebSocket endpoint for audio streaming
- Integrate selected ASR engine
- Stream audio chunks to ASR and return text segments
- Handle start/stop based on wake-word events
## Acceptance Criteria
- [ ] Audio capture working (from mic or WebSocket)
- [ ] WebSocket endpoint for audio streaming
- [ ] ASR engine integrated
- [ ] Text segments returned with timestamps
- [ ] Handles wake-word start/stop events
- [ ] Streaming latency acceptable (< 2s end-to-end)
## Technical Details
Implementation:
- Audio capture: PyAudio, GStreamer, or browser MediaRecorder
- WebSocket server for real-time streaming
- ASR processing: faster-whisper or selected engine
- Return format: JSON with text, timestamps, confidence
## Dependencies
- TICKET-009 (ASR engine selection)
- Wake-word event flow defined (from TICKET-006)
## Related Files
- `home-voice-agent/asr/` (to be created)
## Notes
Can run in parallel with TTS and LLM work. Needs wake-word integration for start/stop.
