What is Coqui?

Coqui is an open-source platform for generating, cloning, and manipulating voice using generative AI. It allows developers and creators to build voice applications without needing specialist audio knowledge. The platform includes tools for text-to-speech synthesis, voice cloning from short audio samples, and voice conversion. Coqui operates on a freemium model, with free open-source tools available for self-hosting and hosted services for those who prefer managed infrastructure. The tool is designed for developers building voice features into applications, content creators producing audio at scale, and researchers working on voice technology.
