ChatTTS-ui is a web interface and API server for text-to-speech synthesis using ChatTTS.
The tool addresses the need to convert written text into natural-sounding speech through a local web interface. It handles mixed Chinese and English text along with numbers and control characters. The underlying ChatTTS model performs the synthesis, and the interface provides both a browser-based UI for interactive use and API endpoints for programmatic access. On first launch, the tool downloads the required model, attempting to fetch from Hugging Face and falling back to Modelscope if that connection fails.
The project suits developers and users who need local, offline text-to-speech capability without relying on cloud services. It works across Windows, Linux, and macOS, with prepackaged executables available for Windows to eliminate setup friction. GPU acceleration is available for systems with Nvidia graphics cards and CUDA installed, significantly speeding up synthesis. Source code deployment is straightforward through standard Python virtual environment setup. The tool is appropriate for applications requiring speech synthesis as a component, whether for accessibility features, audio content generation, or voice-based interfaces.
Development activity shows consistent maintenance with regular updates addressing deployment across multiple platforms and optimization options. The project maintains clear documentation for each operating system's setup process, including both containerized and native deployment paths. Recent work has focused on improving model download reliability and adding GPU acceleration support, indicating responsiveness to performance needs. The codebase remains actively refined with attention to cross-platform compatibility and user experience improvements.
