ChatTTS is a generative text-to-speech model optimized for conversational dialogue scenarios such as LLM assistants, supporting English and Chinese. It offers fine-grained control over prosodic features like laughter, pauses, and interjections, with pretrained models trained on 100,000+ hours of audio.

Use cases

• generate natural speech for chatbot dialogue
• add voice output to an LLM assistant
• synthesize Chinese and English speech with expressive prosody
• control laughter and pauses in generated speech
• build a multi-speaker conversational voice agent
• stream audio generation for real-time voice responses

When to choose

• you need conversational, expressive TTS for a voice assistant
• your application requires Chinese or English dialogue speech with natural prosody
• you want fine-grained control over prosodic features like pauses and laughter

When to avoid

• you need a permissively licensed model for commercial products (AGPL-3.0, academic-only release)
• you need languages other than English or Chinese
• you need production-grade TTS with speaker fine-tuning (released model lacks SFT)
