What is ChatTTS?

ChatTTS is a cutting-edge voice generation model designed specifically for conversational applications such as dialogue tasks for large language model assistants, conversational audio, and video introductions. Trained on approximately 100,000 hours of Chinese and English speech data, it produces high-quality, natural, and expressive speech synthesis. The model excels in capturing fine prosodic features like intonation, pauses, and emotional nuances, making interactions more fluid and lifelike. ChatTTS is open source with plans to release a base model trained on 40,000 hours of data, facilitating further research and development in the AI speech synthesis community.
