ChatTTS is an open-source text-to-speech project focused on generating natural conversational speech for dialogue scenarios. It is designed around use cases such as chat assistants, spoken conversations, and long-form conversational audio rather than only traditional narration. The model supports controllable speech characteristics and can produce expressive output suited to interactive AI applications and voice-based content.

Developers can run ChatTTS locally and integrate it into applications that need generated speech, while the repository provides examples and tooling around inference and model usage. Its conversational orientation makes it useful for prototyping voice agents, dialogue systems, podcasts, and other applications where natural rhythm and speaking style matter. ChatTTS is primarily a model and developer project rather than a polished end-user voice studio, so it is best suited to technical users comfortable working with local AI models.
