 ChatTTS is a text-to-speech model designed specifically for dialogue scenarios such as LLM assistant. It supports both English and Chinese languages. Our model is trained with 100,000+ hours composed of Chinese and English. The open-source version on **[HuggingFace](https://huggingface.co/2Noise/ChatTTS)** is a 40,000 hours pre-trained model without SFT.
