Fish Audio
Fish Audio takes text and audio data and produces multilingual text-to-speech and voice-clones using the S2.1 Pro model. Developers can prototype with a free developer model string, call REST or WebSocket APIs, and receive low-latency first audio suitable for interactive prototypes across 83 languages.
Documented access: a free developer tier using model string s2.1-pro-free (subject to Fair Use Policy); cloud pay-as-you-go at $15 / 1M UTF-8 bytes; and an Enterprise self-host engagement listed at $10k/month with an effective annual floor.Is Fish Audio right for you?
