What is Chattts?

ChatTTS is a text‑to‑speech model optimized for conversational scenarios, supporting both English and Chinese. It is trained on roughly 100,000 hours of spoken language data, yielding natural‑sounding voice output for dialogue and LLM‑assistant applications.

The model is compatible with web, mobile, desktop, and embedded platforms, and can be integrated via provided APIs or SDKs. Users input plain text and receive audio files, facilitating quick deployment in chatbots, video intros, educational modules, and other speech‑synthesis workflows.

The project offers an open‑source base model (40,000 hours of training data) to encourage academic research and developer customization. Control measures such as watermarking and security integration are planned to ensure reliable and safe operation.

ChatTTS includes straightforward installation instructions, clone the repository, install `torch` and the `ChatTTS` package, and call `chat.infer()` to generate speech. The tool’s design emphasizes ease of use, high‑quality synthesis, and versatility across multiple languages and application contexts.
