Fish Audio is a text-to-speech and voice-cloning platform, built by Hanabi AI Inc., with a library the brand says holds over 2 million voices. This review covers what the tool actually does, what's free versus paid, and a couple of places where the brand's own numbers don't quite agree with each other.
What we recommend
What Fish Audio Actually Does
Fish Audio's core products are text-to-speech and voice cloning, alongside speech-to-text, a voice changer, an audiobook-style Story Studio, audio separation, audio translation, and sound effect generation. The brand markets it for video voiceovers, audiobook narration, character voices for games and animation, and conversational chatbots, with a developer API for teams that want to build voice features into their own apps.

Voice Cloning: What It Actually Takes
According to Fish Audio's own FAQ, the platform needs as little as 10 seconds of audio to build a voice clone that can then speak in multiple languages. The brand states its voice library has passed 2,000,000 user-uploaded voices and claims over 8 million users, though those are the platform's own self-reported figures rather than independently audited numbers.
Free Plan vs. Paid: What You Can Actually Do
Fish Audio's FAQ is direct about one restriction that matters a lot: the free plan is for personal use only. If you want to monetize content made with it — a YouTube channel, a paid podcast, anything tied to a business — the brand states you need to upgrade to a paid plan for commercial rights. Beyond that, we could not find a clear, public plan-comparison page listing exact monthly prices; the nav's 'Pricing' link did not resolve to a page showing plan tiers when we checked. The brand does describe its developer API as pay-as-you-go, but doesn't publish clean per-request rates on a page we could confirm, so budget-conscious developers should check the live checkout or contact sales before committing to a workflow.
Language Support — Where the Brand Contradicts Itself
This is worth flagging rather than smoothing over: Fish Audio's own FAQ names eight specific languages it supports — English, Japanese, Korean, Chinese, French, German, Arabic, and Spanish — while a separate 'Multilingual Support' section on the same homepage claims the platform speaks '30+ languages.' We couldn't find a single page reconciling the two claims. If a specific language is a dealbreaker for your project, test it directly on Fish Audio's own generator before you commit to a paid plan.
Is Fish Audio Worth It?
For testing AI voice cloning and text-to-speech on a personal project, Fish Audio's free tier is a reasonable way to hear the quality before paying anything. The catch is squarely commercial use: the moment your content is monetized, the brand's own terms say you need a paid plan, and the exact cost of that plan isn't laid out clearly on a public page we could find. Creators and developers who plan to publish monetized work should get a firm price from Fish Audio directly rather than assuming the free tier covers their use case.
Frequently asked questions
Is Fish Audio free to use?
There's a free tier, but Fish Audio's own FAQ states it's for personal use only. Monetized content — YouTube, paid podcasts, business use — requires upgrading to a paid plan for commercial rights.
How much audio does Fish Audio need to clone a voice?
The brand's FAQ states as little as 10 seconds of audio is enough to create a voice clone that can then speak in multiple languages.
How many languages does Fish Audio actually support?
Fish Audio's FAQ names eight languages by name (English, Japanese, Korean, Chinese, French, German, Arabic, Spanish), while another section of the same homepage advertises '30+ languages.' Test your specific language on the live generator before relying on either number.
