ChatTTS

ChatTTS is an open-source conversational text-to-speech model optimized for dialogue, developed by 2Noise. Trained on 100,000+ hours of English and Chinese conversation data, it excels at generating expressive prosody—pauses, interjections, laughter—for more natural-sounding speech synthesis in assistant and chatbot applications.

Features

Supports English and Chinese
Fine-grained prosody control including pauses, laughter, and interjections
Multiple speaker voices for dialogue scenarios
Pretrained models for ease of integration
Optimized for conversational text inputs
Planned open-source release of base models
