What MeloTTS is

MeloTTS is a free multilingual text-to-speech library from MyShell.ai for creating spoken audio from written text. It supports English, Spanish, French, Chinese, Japanese, and Korean. English examples include American, British, Indian, Australian, and default accents, while the Chinese speaker can combine Chinese and English. Users can work through a Web UI, command-line interface, or Python API, including local installations. The guide covers Linux and macOS setup, with Docker installation described for Windows and some macOS users; local Web UI access is shown at localhost:8888. Python examples offer CPU, CUDA, and MPS device choices, and the project says CPU can provide real-time inference. WAV is the listed export format. The repository includes custom-dataset training instructions and links to live demos. MeloTTS uses the MIT License and permits commercial and non-commercial use, with API access available.
