-## Current Limitations ⚠️
+## Speech Features (Optional)
 
-- 🎙️ Basic voice command support (work in progress)
+The MCP Server includes optional speech processing capabilities:
-- 🧠 Limited advanced NLP capabilities
-- 🔗 Minimal third-party device integration
-- 🐛 Early-stage error handling
 
-## 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
+### Setup
-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
 
-## 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
+2. Start the speech services:
-- 🔌 Improve device compatibility
+```bash
-- 🤖 Expand automation capabilities
+docker-compose up -d
-- 🛡️ Implement more robust error handling
+```
+
+### 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);
+```

 ## Environment Variables
 
-Environment variables override configuration file settings:
+All configuration is managed through environment variables:
 
 ```bash
-MCP_HOST=0.0.0.0
+# Server
-MCP_PORT=8123
+PORT=4000
-MCP_LOG_LEVEL=INFO
+NODE_ENV=development
-MCP_JWT_SECRET=your-secret-key

+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
+### Security Rate Limiting
-```yaml
+Rate limiting is enabled by default to protect against brute force attacks:
-rate_limit:
-  enabled: true
-  requests_per_minute: 100
-  burst: 20
-```
 
-### Caching
+```typescript
-```yaml
+RATE_LIMIT: {
-cache:
+  windowMs: 15 * 60 * 1000,  // 15 minutes
-  enabled: true
+  max: 100  // limit each IP to 100 requests per window
-  ttl: 300  # seconds
+}
-  max_size: 1000  # entries
 ```
 
 ### Logging
-```yaml
+The server uses Bun's built-in logging capabilities with additional configuration:
-logging:
+
-  file: /var/log/mcp-server.log
+```typescript
-  max_size: 10MB
+LOGGING: {
-  backup_count: 5
+  LEVEL: "info",  // debug, info, warn, error
-  format: "%(asctime)s - %(name)s - %(levelname)s - %(message)s"
+  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
+2. Keep .env files secure and never commit them to version control
-3. Regularly backup your configuration
+3. Use different environment files for development, test, and production
-4. Use SSL in production environments
+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:
+The server validates configuration on startup using Zod schemas:
-- Required fields are checked
+- Required fields are checked (e.g., HASS_TOKEN)
 - Value types are verified
-- Ranges are validated
+- Enums are validated (e.g., LOG_LEVEL, WHISPER_MODEL_TYPE)
-- Security settings are assessed
+- Default values are applied when not specified
 
 ## Troubleshooting
 
 Common configuration issues:
-1. Permission denied accessing files
+1. Missing required environment variables
-2. Invalid YAML syntax
+2. Invalid environment variable values
-3. Missing required fields
+3. Permission issues with log directories
-4. Type mismatches in values
+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
