Fish Audio
Open-source voice cloning platform with a community marketplace of 500+ voices and API access for building voice AI applications.
Fish Audio is an open-source voice cloning platform built around Fish Speech, a state-of-the-art text-to-speech model capable of cloning voices from as few as 10 seconds of audio. The platform hosts a community marketplace of 500+ shared voices in multiple languages and provides a REST API for developers building voice AI into applications. Fish Audio supports real-time voice conversion, multi-language TTS in 15+ languages, and emotion control. The open-source Fish Speech model can be self-hosted for teams requiring data privacy or high-volume inference without per-call costs.
