OpenAudio (Fish Audio)

Fish Audio, operating under the Hanabi AI Inc. corporate entity, is an AI voice technology company that develops the OpenAudio model series and the fish.audio platform. The platform offers real-time text-to-speech with emotional control (supporting emotion tags like angry, sad, excited), voice cloning from as little as 10–15 seconds of audio, speech-to-text with multispeaker support, and a library of over 2,000,000 community-uploaded voices across 30+ languages. Its flagship OpenAudio S1 model, launched in June 2025, is positioned as an AI voice actor enabling real-time emotional control for games, animation, audiobooks, and conversational chatbots. Fish Audio also provides developer APIs with ultra-low latency streaming and open-source model releases under the Fish Speech project on GitHub.
