Fish Audio develops AI speech generation and speech-to-text models and offers both open-source releases and paid API plans for creators, teams, and enterprises. The company has launched five models in the last year—three of which are open-sourced—and its S2.1 Pro model is available only through its paid API. Fish Audio reports more than 8 million users and $21 million in annual recurring revenue, and its GitHub Fish Speech repository has over 31,000 stars. It offers paid monthly plans that unlock generation minutes and voice cloning features, and it also runs enterprise APIs used by companies including HeyGen, Sanas and Plaud. The startup plans to release an audio understanding model this year and is building a speech-to-speech model as part of its roadmap. Fish Audio has also implemented an automated takedown process and creator verification flows to address consent and licensing concerns around uploaded voices.
