F5 TTS

Flow-matching TTS model with fast inference and natural zero-shot voice cloning

Voice AIFree

F5-TTS is an open-source text-to-speech model that uses flow matching for fast, high-quality speech synthesis with zero-shot voice cloning from a short reference audio clip. It is notable for its speed compared to diffusion-based models while maintaining high output quality, making it practical for real-time or near-real-time applications. Developers building voice assistants, dubbing tools, and AI companion applications use F5-TTS as a production-capable open-source alternative to commercial voice APIs.
