Fish Audio raises $50M seed to build AI voice models for creators and enterprises

Fish Audio, a Palo Alto startup building AI voice models, raised $50 million in a seed round to expand its library and enterprise offerings. The company said it has more than 15,000 natural-language controls and that, since launching last year, over 8 million people use its open-source or hosted models. Fish Audio generates $21 million in annual recurring revenue, and has launched five models in the past year, including four speech generation models and one speech-to-text model. Three generation models are open-sourced, while its latest S2.1 Pro is available only via paid API. The round was led by Coreline Ventures and Capital Today.
