The AI voice startup has crossed 8 million users and $21M in annual recurring revenue as investor appetite for generative audio tools grows
Fish Audio just closed a major seed funding round to accelerate development of its text-to-speech models. The company reports more than 8 million users across its open-source and hosted model offerings, alongside $21 million in annual recurring revenue.
What Fish Audio actually does #
Fish Audio builds text-to-speech technology that converts written words into natural-sounding human voices. The company offers both an open-source version of its models and a hosted API product, which lets developers plug voice synthesis directly into their own applications.
Its flagship model family, the Fish-Speech and S2 series, supports more than 80 languages. The company published technical reports on its S2 and S2 Pro models in March 2026, and its benchmarks show a word error rate of 0.54% in Chinese and 0.99% in English.
Real-time streaming and instant voice cloning are two of the platform’s headline features. Fish Audio also runs a community marketplace where developers and creators can share and monetize voice models they have built on top of the platform.
The funding picture and what it signals #
The company reached a valuation of $500 million following a $30 million venture financing round in 2025. No lead investor was publicly named in connection with that round.
Fish Audio itself has no reported affiliation with blockchain technology or crypto tokens. Its business is straightforwardly an AI software company funded by venture capital, not a Web3 project.
