Coqui TTS (XTTS)

Coqui TTS boasts the most extensive library of pre-trained TTS models, offering over 1,100 language models. Its YourTTS model enables zero-sample multilingual voice cloning for 3-second audio clips, as well as cross-lingual synthesis (producing English speech using Chinese input samples). It also provides a complete training framework that allows users to develop their own custom TTS models. Although the company behind it has ceased operations, the open-source community continues to maintain it, keeping the code and models available for use. It is suitable for research purposes and scenarios that require large numbers of pre-trained models.
