## 🚀 Quick Start

> [!IMPORTANT]
> This project includes `Matcha-TTS` as a submodule. To ensure it is cloned correctly, please use the `--recursive` flag with `git clone`:
> ```bash
> git clone --recursive https://github.com/EitanWong/CosyVoice-Enhanced.git
> ```
> If you have already cloned the repository without the submodule, you can initialize it by running:
> ```bash
> git submodule update --init --recursive
> ```



### Option 1: Docker Deployment (Recommended)

```bash
# Clone the repository
git clone --recursive https://github.com/EitanWong/CosyVoice-Enhanced.git
cd CosyVoice

# Download models (choose your preferred model)
python scripts/download.py --model CosyVoice2-0.5B
# or: python scripts/download.py --model CosyVoice-300M-SFT

# Start with Docker Compose
cd docker
docker-compose up -d

# Check service status
docker-compose logs -f cosyvoice-api
```

**🎯 API ready at**: `http://localhost:9996`  
**🌐 Web UI ready at**: `http://localhost:9996/webui`

### 🖱️ One-Click Scripts (Windows)

For Windows users, we provide convenient batch scripts in the `scripts/` directory:

```bash
# Navigate to project root directory first
cd CosyVoice

# Then use any of these one-click scripts:
scripts\docker-compose-up.bat      # Start services in background
scripts\docker-compose-stop.bat    # Stop services (containers remain)
scripts\docker-compose-restart.bat # Restart all services
scripts\docker-compose-down.bat    # Stop and remove containers
```

**📋 Script Features:**
- **🔍 Auto-detection**: Automatically detects and starts Docker Desktop if needed
- **⏱️ Smart waiting**: Waits for Docker to be ready before proceeding
- **📊 Status feedback**: Clear progress indicators and error messages
- **🛡️ Error handling**: Graceful failure handling with helpful messages

**⚠️ Important Notes:**
- Run scripts from the **project root directory** (not from `scripts/` folder)
- Scripts automatically navigate to the correct `docker/` directory
- First-time startup may take 2-3 minutes for Docker Desktop initialization
- Ensure Docker Desktop is installed before using these scripts

### Option 2: Local Installation

```bash
# Create conda environment
conda create -n cosyvoice python=3.10 -y
conda activate cosyvoice

# Install dependencies
pip install -r requirements.txt

# Download models
python scripts/download.py --model CosyVoice2-0.5B

# Start API server
python api/api.py --model pretrained_models/CosyVoice2-0.5B --port 9996

# Start Web UI (in another terminal)
python api/webui.py --model_dir pretrained_models/CosyVoice2-0.5B --port 7860
```

## 📚 Usage Examples

### 🔌 OpenAI Compatible API

Replace your OpenAI TTS calls with CosyVoice seamlessly:

```python
from openai import OpenAI

# Point to your CosyVoice server
client = OpenAI(
    api_key="dummy-key",  # Not required but expected by OpenAI client
    base_url="http://localhost:9996/v1"
)

# Generate speech (identical to OpenAI API)
response = client.audio.speech.create(
    model="tts-1",
    voice="中文女", 
    input="Hello! This is CosyVoice speaking with enhanced quality.",
    response_format="mp3"
)

# Save the audio
with open("speech.mp3", "wb") as f:
    f.write(response.content)
```

## 📖 API Reference

### Speech Generation Endpoint

**POST** `/v1/audio/speech`

```json
{
  "model": "tts-1",                    // Model identifier
  "input": "Text to synthesize",       // Input text (up to 4096 chars)
  "voice": "中文女",                    // Voice selection
  "response_format": "mp3",            // Audio format
  "speed": 1.0,                        // Playback speed (0.25-4.0)
  "stream": false                      // Enable streaming response
}
```
### Health Check

**GET** `/health` - Returns service status and model information

## 🔧 Troubleshooting

### Common Issues

1. **CUDA Out of Memory**
   ```bash
   export CUDA_VISIBLE_DEVICES=0
   # Use FP16 mode: --fp16
   ```

2. **VLLM Installation Issues**
   ```bash
   # Create separate environment for VLLM
   conda create -n cosyvoice_vllm --clone cosyvoice
   conda activate cosyvoice_vllm
   pip install vllm==0.9.0
   ```

3. **Audio Quality Issues**
   ```bash
   # Install sox for better audio processing
   sudo apt-get install sox libsox-dev  # Ubuntu
   brew install sox                      # macOS
   ```

4. **Docker Permission Issues**
   ```bash
   # Add user to docker group
   sudo usermod -aG docker $USER
   ```

### Performance Tuning

- **For CPU inference**: Use `--fp16` and `--load-jit`
- **For GPU inference**: Enable `--load-vllm` (CosyVoice2 only)
- **For production**: Use Docker with health checks and proper resource limits
