```
|
|
|
|
### Step 3: Configure Environment
|
|
```bash
|
|
cd ~/atlas/home-voice-agent
|
|
|
|
# Create .env file
|
|

|
```
|
|
|
|
### Step 4: Test Core Services
|
|
```bash
|
|
# Test MCP server

## 🎤 Voice I/O Setup (When Ready)
|
|
|
|
### Wake-Word Detection (TICKET-006)
|
|
**Status**: Ready to implement
|
|
**Requirements**:
|
|
- USB microphone connected
|
|
- Python audio libraries (PyAudio, sounddevice)
|
|
- Wake-word engine (openWakeWord or Porcupine)
|
|
|
|
**Implementation**:
|
|
```bash
|
|
# Install audio dependencies
|
|
sudo apt install -y portaudio19-dev python3-pyaudio
|
|
|
|
# Install wake-word engine
|
|
pip install openwakeword # or porcupine
|
|
```
|
|
|
|
### ASR Service (TICKET-010)
|
|
**Status**: Ready to implement
|
|
**Requirements**:
|
|
- faster-whisper or Whisper.cpp
|
|
- Audio capture (PyAudio)
|
|
- WebSocket server
|
|
|
|
**Implementation**:
|
|
```bash
|
|
# Install faster-whisper
|
|
pip install faster-whisper
|
|
|
|
# Or use Whisper.cpp (lighter weight for Pi5)
|
|
# See ASR_EVALUATION.md for details
|
|
```
|
|
|
|
**Note**: ASR can run on:
|
|
- **Option A**: Pi5 CPU (slower, but works)
|
|
- **Option B**: RTX 4080 server (recommended, faster)
|
|
|
|
### TTS Service (TICKET-014)
|
|
**Status**: Ready to implement
|
|
**Requirements**:
|
|
- Piper, Mimic 3, or Coqui TTS
|
|
- Audio output (speakers/headphones)
|
|
|
|
**Implementation**:
|
|
```bash
|
|
# Install Piper (lightweight, recommended for Pi5)
|
|
# See TTS_EVALUATION.md for details
|
|
```
|
|
|
|
## 🔧 Pi5-Specific Considerations
|
|
|
|
### Performance
|
|
- **Pi5 Specs**: Much faster than Pi4, but still ARM
|
|
- **Recommendation**: Run wake-word on Pi5, ASR on 4080 server
|
|
- **Memory**: 4GB+ RAM recommended
|
|
- **Storage**: Use fast microSD (Class 10, A2) or USB SSD
|
|
|
|
### Power
|
|
- **Official 27W power supply required** for Pi5
|
|
- **Cooling**: Active cooling recommended for sustained load
|
|
- **Power consumption**: ~5-10W idle, ~15-20W under load
|
|
|
|
### Audio
|
|
- **USB microphones**: Plug-and-play, recommended
|
|
- **3.5mm audio**: Can use for output (speakers)
|
|
- **HDMI audio**: Alternative for output
|
|
|
|
### Network
|
|
- **Ethernet**: Recommended for stability
|
|
- **WiFi**: Works, but may have latency
|
|
- **Firewall**: May need to open port 8000
|
|
