Fish Audio

Fish Audio is an AI voice platform for creating realistic speech with tools for text-to-speech, voice cloning, and speech-to-text. Generate expressive voice performances using emotion tags, then refine output with pro audio utilities for creator- and studio-style results.

Create more than narration: clone a voice for consistent character or persona work, generate publish-ready audiobook-style audio, and turn scripts into scene-matched voiceovers for videos and explainers. For interactive needs, it also supports character voices and conversational chatbot voice for natural, low-latency responses.

Built for scale, Fish Audio supports over 2,000,000 voices in its voice library and offers an API for developers who want production-ready voice agents—from real-time streaming to instant voice cloning. Explore or start free, then build workflows for multilingual voice content and voice-driven applications.

What is Fish Audio?

Fish Audio is an AI voice platform built as API-first infrastructure. Its latest model, S2.1 Pro handles text-to-speech generation, voice cloning, and automatic speech recognition (ASR) across 83 languages from a single endpoint, with time-to-first-audio in the 70–100ms range.

That latency spec is what separates it from batch-only platforms: at under 100ms, voice generation can run inline in real-time products — conversational IVR, live voice agents, interactive avatars — without a perceptible pause. It is used by developers integrating voice into applications, agencies managing high-volume content production, and enterprise teams running training, localization, and customer-service audio at scale.

Is Fish Audio free to use?

Yes — Fish Audio has a free tier, but it is limited to personal, non-commercial use. Using free-tier output in client deliverables, paid campaigns, or any commercial context is a contract violation, not a cost optimization. Commercial rights start at the Plus plan. This is the single most common compliance mistake teams make when adopting the platform informally.

What is Fish Audio's pricing?

Fish Audio has two distinct pricing structures — conflating them is a common budgeting error:

Free Personal use only — not for commercial content $0 Plus Plan Commercial rights · monthly generation allowance $11/mo API (usage-based) $15/1M characters

How does Fish Audio voice cloning work?

Fish Audio generates a reusable voice model from a reference audio sample as short as 15 seconds. Once created, the cloned voice is stored as an asset and callable as an API parameter — ensuring every subsequent generation matches that voice exactly, regardless of script or timing. Commercial use of a cloned voice requires a paid plan. Any organization deploying voice cloning should have an internal policy covering consent and authorization before any voice sample is submitted.

What languages does Fish Audio support?

The S2.1 Pro model covers 83 languages from a single endpoint — not routed to separate underlying models per language. This matters architecturally: a single API integration handles every language in parallel, which is what makes simultaneous multilingual localization practical rather than sequential. Training data for S2 spanned more than 10 million hours across roughly 80 languages.

What is Fish Audio's community voice library?

Fish Audio hosts a community voice library with over 2,000,000 voices contributed by users. These are available to explore and use within platform terms — community voices should be treated as platform-licensed assets rather than cleared-for-any-commercial-use inventory. Check per-voice license terms before deploying in a client deliverable or production application.
