Overview
ChatTTS is a voice generation model designed specifically for conversational scenarios — the dialogue tasks of large language model (LLM) assistants, plus conversational audio and video introductions. Trained on approximately 10 million hours of Chinese and English data, it delivers high quality and naturalness in speech synthesis.
It supports both Chinese and English, is well-suited for dialog tasks, and the project team plans to open source a trained base model. The team is committed to improving controllability, adding watermarks and integrating with LLMs for safety and reliability.
With 20K+ GitHub stars, ChatTTS is easy to use — just input text and generate corresponding voice files. A free online demo and free AI voice cloning (via Voicv) are available.
