ChatTTS is a generative speech model specifically optimized for dialogue-driven applications. Leveraging advanced neural architectures, it produces natural and expressive speech with controllable prosody and speaker similarity. Users can specify speaker identities, adjust speaking rate and pitch, and fine-tune emotional tone to match diverse conversational contexts. The model is open-source and hosted on Hugging Face, enabling seamless integration via Python APIs or direct model inference in local environments. ChatTTS supports real-time synthesis, batch processing, and multi-lingual capabilities, making it suitable for chatbots, virtual assistants, interactive storytelling, and accessibility tools that require dynamic, human-like voice interactions.
