What Fish Audio S2 does
Fish Audio S2, operated by Hanabi AI Inc. (a Delaware-incorporated company headquartered in Mountain View, California), is an AI voice generation platform that provides text-to-speech, speech-to-text, voice cloning, and voice design through a self-serve website (fish.audio), a REST API, and mobile applications. The company maintains a proprietary model family — Fish Speech, Fish Audio S1, Fish Audio S2, and the flagship Fish Audio S2.1 Pro — that supports real-time, emotionally controllable voice generation across more than 30 languages, with native-quality pronunciation in 8 (English, Japanese, Korean, Chinese, French, German, Arabic, Spanish).
The product surface is built around a core TTS engine with Voice Cloning that creates a digital voice model from 10-15 seconds of audio, Voice Design for prompt-based voice creation, Story Studio for ACX/Audible-spec-compliant audiobook production, and a Voice Library marketplace containing over 2,000,000 community-uploaded voices. Supporting modules include Voice Changer, Audio Separation, Audio Translation, Sound Effects, Speech-to-Text transcription, and a Voice Agent enterprise solution for customer-support applications. Development is sustained by an open-source community through GitHub (fishaudio), Discord, and the OpenAudio research arm, which together with 18+ integration partnerships (HeyGen, OpenArt, Novita AI, Viggle, VoiceDrop, Pictoria, and others) form a distribution ecosystem.
Fish Audio monetizes through a freemium tiered subscription (Free, Plus at $11/month, Pro at $75/month, Max at $749/month), pay-as-you-go API pricing ($15 per million UTF-8 bytes for TTS, $0.36 per audio hour for ASR), and custom enterprise contracts that bundle SOC 2 Type II compliance, zero data retention, on-premise deployment, and custom SSO. Its go-to-market is primarily product-led and self-serve, with developer-focused API documentation for technical buyers and direct enterprise sales for compliance-driven customers. The platform serves three primary segments — content creators and YouTubers, developers building voice-enabled applications, and enterprises with regulatory requirements — with gaming, animation, and audiobook publishing as secondary verticals.
