## Current Limitations ⚠️
## Speech Features (Optional)
- 🎙️ Basic voice command support (work in progress)
- 🧠 Limited advanced NLP capabilities
- 🔗 Minimal third-party device integration
- 🐛 Early-stage error handling
The MCP Server includes optional speech processing capabilities:
## Contributing 🤝
### Prerequisites
1. Docker installed and running
2. NVIDIA GPU with CUDA support (optional)
3. At least 4GB RAM (8GB+ recommended for larger models)
1. Fork the repository
2. Create a feature branch:
```bash
git checkout -b feature/your-feature
```
3. Make your changes
4. Run tests:
```bash
bun test
```
5. Submit a pull request
### Setup
## Roadmap 🗺️
1. Enable speech features in your .env:
```bash
ENABLE_SPEECH_FEATURES=true
ENABLE_WAKE_WORD=true
ENABLE_SPEECH_TO_TEXT=true
WHISPER_MODEL_PATH=/models
WHISPER_MODEL_TYPE=base
```
- 🎤 Enhance voice command processing
- 🔌 Improve device compatibility
- 🤖 Expand automation capabilities
- 🛡️ Implement more robust error handling
2. Start the speech services:
```bash
docker-compose up -d
```
### Available Models
Choose a model based on your needs:
- `tiny.en`: Fastest, basic accuracy
- `base.en`: Good balance (recommended)
- `small.en`: Better accuracy, slower
- `medium.en`: High accuracy, resource intensive
- `large-v2`: Best accuracy, very resource intensive
### Usage
1. Wake word detection listens for:
- "hey jarvis"
- "ok google"
- "alexa"
2. After wake word detection:
- Audio is automatically captured
- Speech is transcribed
- Commands are processed
3. Manual transcription is also available:
```typescript
const speech = speechService.getSpeechToText();
const text = await speech.transcribe(audioBuffer);
```
## Configuration
See [Configuration Guide](docs/configuration.md) for detailed settings.
## API Documentation
See [API Documentation](docs/api/index.md) for available endpoints.
## Development
See [Development Guide](docs/development/index.md) for contribution guidelines.

@@ -4,103 +4,267 @@ This document provides detailed information about configuring the Home Assistant
## Configuration File Structure
The MCP Server uses a hierarchical configuration structure:
The MCP Server uses environment variables for configuration, with support for different environments (development, test, production):
```yaml
server:
host: 0.0.0.0
port: 8123
log_level: INFO
security:
jwt_secret: YOUR_SECRET_KEY
allowed_origins:
- http://localhost:3000
- https://your-domain.com
devices:
scan_interval: 30
default_timeout: 10
```bash
# .env, .env.development, or .env.test
PORT=4000
NODE_ENV=development
HASS_HOST=http://192.168.178.63:8123
HASS_TOKEN=your_token_here
JWT_SECRET=your_secret_key
```
## Server Settings
### Basic Server Configuration
- `host`: Server binding address (default: 0.0.0.0)
- `port`: Server port number (default: 8123)
- `log_level`: Logging level (INFO, DEBUG, WARNING, ERROR)
- `PORT`: Server port number (default: 4000)
- `NODE_ENV`: Environment mode (development, production, test)
- `HASS_HOST`: Home Assistant instance URL
- `HASS_TOKEN`: Home Assistant long-lived access token
### Security Settings
- `jwt_secret`: Secret key for JWT token generation
- `allowed_origins`: CORS allowed origins list
- `ssl_cert`: Path to SSL certificate (optional)
- `ssl_key`: Path to SSL private key (optional)
- `JWT_SECRET`: Secret key for JWT token generation
- `RATE_LIMIT`: Rate limiting configuration
- `windowMs`: Time window in milliseconds (default: 15 minutes)
- `max`: Maximum requests per window (default: 100)
### Device Management
- `scan_interval`: Device state scan interval in seconds
- `default_timeout`: Default device command timeout
- `retry_attempts`: Number of retry attempts for failed commands
### WebSocket Settings
- `SSE`: Server-Sent Events configuration
- `MAX_CLIENTS`: Maximum concurrent clients (default: 1000)
- `PING_INTERVAL`: Keep-alive ping interval in ms (default: 30000)
### Speech Features (Optional)
- `ENABLE_SPEECH_FEATURES`: Enable speech processing features (default: false)
- `ENABLE_WAKE_WORD`: Enable wake word detection (default: false)
- `ENABLE_SPEECH_TO_TEXT`: Enable speech-to-text conversion (default: false)
- `WHISPER_MODEL_PATH`: Path to Whisper models directory (default: /models)
- `WHISPER_MODEL_TYPE`: Whisper model type (default: base)
- Available models: tiny.en, base.en, small.en, medium.en, large-v2
## Environment Variables
Environment variables override configuration file settings:
All configuration is managed through environment variables:
```bash
MCP_HOST=0.0.0.0
MCP_PORT=8123
MCP_LOG_LEVEL=INFO
MCP_JWT_SECRET=your-secret-key
# Server
PORT=4000
NODE_ENV=development
# Home Assistant
HASS_HOST=http://your-hass-instance:8123
HASS_TOKEN=your_token_here
# Security
JWT_SECRET=your-secret-key
# Logging
LOG_LEVEL=info
LOG_DIR=logs
LOG_MAX_SIZE=20m
LOG_MAX_DAYS=14d
LOG_COMPRESS=true
LOG_REQUESTS=true
# Speech Features (Optional)
ENABLE_SPEECH_FEATURES=false
ENABLE_WAKE_WORD=false
ENABLE_SPEECH_TO_TEXT=false
WHISPER_MODEL_PATH=/models
WHISPER_MODEL_TYPE=base
```
## Advanced Configuration
### Rate Limiting
```yaml
rate_limit:
enabled: true
requests_per_minute: 100
burst: 20
```
### Security Rate Limiting
Rate limiting is enabled by default to protect against brute force attacks:
### Caching
```yaml
cache:
enabled: true
ttl: 300 # seconds
max_size: 1000 # entries
```typescript
RATE_LIMIT: {
windowMs: 15 * 60 * 1000, // 15 minutes
max: 100 // limit each IP to 100 requests per window
}
```
### Logging
```yaml
logging:
file: /var/log/mcp-server.log
max_size: 10MB
backup_count: 5
format: "%(asctime)s - %(name)s - %(levelname)s - %(message)s"
The server uses Bun's built-in logging capabilities with additional configuration:
```typescript
LOGGING: {
LEVEL: "info", // debug, info, warn, error
DIR: "logs",
MAX_SIZE: "20m",
MAX_DAYS: "14d",
COMPRESS: true,
TIMESTAMP_FORMAT: "YYYY-MM-DD HH:mm:ss:ms",
LOG_REQUESTS: true
}
```
### Speech-to-Text Configuration
When speech features are enabled, you can configure the following options:
```typescript
SPEECH: {
ENABLED: false, // Master switch for all speech features
WAKE_WORD_ENABLED: false, // Enable wake word detection
SPEECH_TO_TEXT_ENABLED: false, // Enable speech-to-text
WHISPER_MODEL_PATH: "/models", // Path to Whisper models
WHISPER_MODEL_TYPE: "base", // Model type to use
}
```
Available Whisper models:
- `tiny.en`: Fastest, lowest accuracy
- `base.en`: Good balance of speed and accuracy
- `small.en`: Better accuracy, slower
- `medium.en`: High accuracy, much slower
- `large-v2`: Best accuracy, very slow
For production deployments, we recommend using system tools like `logrotate` for log management.
Example logrotate configuration (`/etc/logrotate.d/mcp-server`):
```
/var/log/mcp-server.log {
daily
rotate 7
compress
delaycompress
missingok
notifempty
create 644 mcp mcp
}
```
## Best Practices
1. Always use environment variables for sensitive information
2. Keep configuration files in a secure location
3. Regularly backup your configuration
4. Use SSL in production environments
2. Keep .env files secure and never commit them to version control
3. Use different environment files for development, test, and production
4. Enable SSL/TLS in production (preferably via reverse proxy)
5. Monitor log files for issues
6. Regularly rotate logs in production
7. Start with smaller Whisper models and upgrade if needed
8. Consider GPU acceleration for larger Whisper models
## Validation
The server validates configuration on startup:
- Required fields are checked
The server validates configuration on startup using Zod schemas:
- Required fields are checked (e.g., HASS_TOKEN)
- Value types are verified
- Ranges are validated
- Security settings are assessed
- Enums are validated (e.g., LOG_LEVEL, WHISPER_MODEL_TYPE)
- Default values are applied when not specified
## Troubleshooting
Common configuration issues:
1. Permission denied accessing files
2. Invalid YAML syntax
3. Missing required fields
4. Type mismatches in values
1. Missing required environment variables
2. Invalid environment variable values
3. Permission issues with log directories
4. Rate limiting too restrictive
5. Speech model loading failures
6. Docker not available for speech features
7. Insufficient system resources for larger models

```
## Speech Features
### Model Selection
Choose a model based on your needs:
| Model | Size | Memory Required | Speed | Accuracy |
|------------|-------|-----------------|-------|----------|
| tiny.en | 75MB | 1GB | Fast | Basic |
| base.en | 150MB | 2GB | Good | Good |
| small.en | 500MB | 4GB | Med | Better |
| medium.en | 1.5GB | 8GB | Slow | High |
| large-v2 | 3GB | 16GB | Slow | Best |
### GPU Acceleration
When `WHISPER_DEVICE=cuda`:
- NVIDIA GPU with CUDA support required
- Significantly faster processing
- Higher memory requirements
### Wake Word Detection
- Multiple wake words supported via comma-separated list
- Adjustable sensitivity (0-1):
- Lower values: Fewer false positives, may miss some triggers
- Higher values: More responsive, may have false triggers
- Default (0.5): Balanced detection
### Best Practices
1. Model Selection:
- Start with `base.en` model
- Upgrade if better accuracy needed
- Downgrade if performance issues
2. Resource Management:
- Monitor memory usage
- Use GPU acceleration when available
- Consider model size vs available resources
3. Wake Word Configuration:
- Use distinct wake words
- Adjust sensitivity based on environment
- Limit number of wake words for better performance

# Speech Features
The Home Assistant MCP Server includes powerful speech processing capabilities powered by fast-whisper and custom wake word detection. This guide explains how to set up and use these features effectively.
## Overview
The speech processing system consists of two main components:
1. Wake Word Detection - Listens for specific trigger phrases
2. Speech-to-Text - Transcribes spoken commands using fast-whisper
## Setup
### Prerequisites
1. Docker environment:
```bash
docker --version # Should be 20.10.0 or higher
```
2. For GPU acceleration:
- NVIDIA GPU with CUDA support
- NVIDIA Container Toolkit installed
- NVIDIA drivers 450.80.02 or higher
### Installation
1. Enable speech features in your `.env`:
```bash
ENABLE_SPEECH_FEATURES=true
ENABLE_WAKE_WORD=true
ENABLE_SPEECH_TO_TEXT=true
```
2. Configure model settings:
```bash
WHISPER_MODEL_PATH=/models
WHISPER_MODEL_TYPE=base
WHISPER_LANGUAGE=en
WHISPER_TASK=transcribe
WHISPER_DEVICE=cuda # or cpu
```
3. Start the services:
```bash
docker-compose up -d
```
## Usage
### Wake Word Detection
The wake word detector continuously listens for configured trigger phrases. Default wake words:
- "hey jarvis"
- "ok google"
- "alexa"
Custom wake words can be configured:
```bash
WAKE_WORDS=computer,jarvis,assistant
```
When a wake word is detected:
1. The system starts recording audio
2. Audio is processed through the speech-to-text pipeline
3. The resulting command is processed by the server
### Speech-to-Text
#### Automatic Transcription
After wake word detection:
1. Audio is automatically captured (default: 5 seconds)
2. The audio is transcribed using the configured whisper model
3. The transcribed text is processed as a command
#### Manual Transcription
You can also manually transcribe audio using the API:
```typescript
// Using the TypeScript client
import { SpeechService } from '@ha-mcp/client';
const speech = new SpeechService();
// Transcribe from audio buffer
const buffer = await getAudioBuffer();
const text = await speech.transcribe(buffer);
// Transcribe from file
const text = await speech.transcribeFile('command.wav');
```
```javascript
// Using the REST API
POST /api/speech/transcribe
Content-Type: multipart/form-data
file: <audio file>
```
### Event Handling
The system emits various events during speech processing:
```typescript
speech.on('wakeWord', (word: string) => {
console.log(`Wake word detected: ${word}`);
});
speech.on('listening', () => {
console.log('Listening for command...');
});
speech.on('transcribing', () => {
console.log('Processing speech...');
});
speech.on('transcribed', (text: string) => {
console.log(`Transcribed text: ${text}`);
});
speech.on('error', (error: Error) => {
console.error('Speech processing error:', error);
});
```
## Performance Optimization
### Model Selection
Choose an appropriate model based on your needs:
1. Resource-constrained environments:
- Use `tiny.en` or `base.en`
- Run on CPU if GPU unavailable
- Limit concurrent processing
2. High-accuracy requirements:
- Use `small.en` or `medium.en`
- Enable GPU acceleration
- Increase audio quality
3. Production environments:
- Use `base.en` or `small.en`
- Enable GPU acceleration
- Configure appropriate timeouts
### GPU Acceleration
When using GPU acceleration:
1. Monitor GPU memory usage:
```bash
nvidia-smi -l 1
```
2. Adjust model size if needed:
```bash
WHISPER_MODEL_TYPE=small # Decrease if GPU memory limited
```
3. Configure processing device:
```bash
WHISPER_DEVICE=cuda # Use GPU
WHISPER_DEVICE=cpu # Use CPU if GPU unavailable
```
## Troubleshooting
### Common Issues
1. Wake word detection not working:
- Check microphone permissions
- Adjust `WAKE_WORD_SENSITIVITY`
- Verify wake words configuration
2. Poor transcription quality:
- Check audio input quality
- Try a larger model
- Verify language settings
3. Performance issues:
- Monitor resource usage
- Consider smaller model
- Check GPU acceleration status
### Logging
Enable debug logging for detailed information:
```bash
LOG_LEVEL=debug
```
Speech-specific logs will be tagged with `[SPEECH]` prefix.
## Security Considerations
1. Audio Privacy:
- Audio is processed locally
- No data sent to external services
- Temporary files automatically cleaned
2. Access Control:
- Speech endpoints require authentication
- Rate limiting applies to transcription
- Configurable command restrictions
3. Resource Protection:
- Timeouts prevent hanging
- Memory limits enforced
- Graceful error handling
