## About

This is a **complete MegaTTS3 model** with **WaveVAE support** for zero-shot voice cloning. Unlike the original ByteDance release, this includes the full WaveVAE encoder/decoder, enabling direct voice cloning from audio samples.

**Key Features:**
- 🎯 Zero-shot voice cloning from any 3-24 second audio sample
- 🌍 Bilingual: Chinese, English, and code-switching
- ⚡ Efficient: 0.45B parameter diffusion transformer
- 🔧 Complete: Includes WaveVAE (missing from original)
- 🎛️ Controllable: Adjustable voice similarity and clarity
- 💻 Windows ready: One-click installer available

## Quick Start

### Installation
**[📥 One-Click Windows Installer](https://github.com/Saganaki22/MegaTTS3-WaveVAE/releases/tag/Installer)** - Automated setup with GPU detection

Or see [manual installation](https://github.com/Saganaki22/MegaTTS3-WaveVAE#installation) for advanced users.

### Usage Examples

```bash
# Basic voice cloning
python tts/infer_cli.py --input_wav 'reference.wav' --input_text "Your text here" --output_dir ./output

# Better quality settings
python tts/infer_cli.py --input_wav 'reference.wav' --input_text "Your text here" --output_dir ./output --p_w 2.0 --t_w 3.0

# Web interface (easiest)
python tts/megatts3_gradio.py
# Then open http://localhost:7929
```

## Model Components

- **Diffusion Transformer**: 0.45B parameter TTS model
- **WaveVAE**: High-quality audio encoder/decoder
- **Aligner**: Speech-text alignment model  
- **G2P**: Grapheme-to-phoneme converter

## Parameters
- `--p_w` (Intelligibility): 1.0-5.0, higher = clearer speech
- `--t_w` (Similarity): 0.0-10.0, higher = more similar to reference
- **Tip**: Set t_w 0-3 points higher than p_w

## Requirements
- Windows 10/11 or Linux
- Python 3.10
- 8GB+ RAM, NVIDIA GPU recommended
- 5GB+ storage space
