 Introduction
 [!Note]
 This repo contains the algorithm infrastructure and some simple examples.

 [!Tip]
 For the extended end-user products, please refer to the index repo Awesome-ChatTTS maintained by the community.  
 You can find a diagram visualization of the codebase here.

ChatTTS is a text-to-speech model designed specifically for dialogue scenarios such as LLM assistant.

 Supported Languages
- [x] English
- [x] Chinese
- [ ] Coming Soon...

 Highlights
 You can refer to this video on Bilibili for the detailed description.

1. Conversational TTS: ChatTTS is optimized for dialogue-based tasks, enabling natural and expressive speech synthesis. It supports multiple speakers, facilitating interactive conversations.
2. Fine-grained Control: The model could predict and control fine-grained prosodic features, including laughter, pauses, and interjections. 
3. Better Prosody: ChatTTS surpasses most of open-source TTS models in terms of prosody. We provide pretrained models to support further research and development.

 Dataset & Model
 [!Important]
 The released model is for academic purposes only.

- The main model is trained with Chinese and English audio data of 100,000+ hours.
- The open-source version on HuggingFace is a 40,000 hours pre-trained model without SFT.

 Roadmap
- [x] Open-source the 40k-hours-base model and spk_stats file.
- [x] Streaming audio generation.
- [x] Open-source DVAE encoder and zero shot inferring code.
- [ ] Multi-emotion controlling.
- [ ] ChatTTS.cpp (new repo in 2noise org is welcomed)

 The model

The model is published under CC BY-NC 4.0 license. It is intended for educational and research use, and should not be used for any commercial or illegal purposes.

The data obtained from publicly available sources, and the authors do not claim any ownership or copyright over the data.

 Disclaimer

ChatTTS is a powerful text-to-speech system. However, it is very important to utilize this technology responsibly and ethically. To limit the use of ChatTTS, we added a small amount of high-frequency noise during the training of the 40,000-hour model, and compressed the audio quality as much as possible using MP3 format, to prevent malicious actors from potentially using it for criminal purposes. At the same time, we have internally trained a detection model and plan to open-source it in the future.
