Create a cloned voice from 15–30 seconds of reference audio, generate expressive speech with laughter and sighs, and produce multilingual narration on the go. Hanabi AI Inc.'s Fish Audio delivers these capabilities to iPhone and web users, combining instant voice cloning, Story Studio for long-form projects, and a developer-facing REST API. It targets content creators and indie developers who need low-latency, emotionally controlled speech for social clips, audiobooks, or interactive agents.

What the tool actually generates and how

Fish Audio performs two core tasks: voice cloning from short samples and expressive text-to-speech. The app clones a voice using as little as 15 to 30 seconds of clear reference audio and can insert non-verbal cues such as laughter, breathing, and sighs. It also offers a Story Studio for long-form narration, an audio-separation feature for stems, a voice changer, and access to a community library of over 2 million voice models.

Does it affect device responsiveness or suit real-time use?

The platform advertises ultra-low latency generation, which supports real-time applications and live interaction scenarios when used via the app or the high-performance REST API. The mobile client requires iOS 15.0 or later, and the company provides Android and web access as well. These distribution options let you run quick tests on-device and offload heavier batch work to the web service, reducing on-phone processing for long projects.

Is it safe and practical for production projects?

Fish Audio exposes developer tools (REST API and SDKs) for integration and ships a large community voice library, which implies a platform-level content ecosystem. The cloning threshold of 15–30 seconds is explicit, so production workflows must manage source audio quality for reliable results. User feedback notes a credit-based model that can constrain high-volume producers, so planning for usage limits matters when preparing large-scale runs.

Who can operate it and what technical skills are needed?

The app serves two main operator profiles: creators using the mobile Story Studio and developers integrating the API. Story Studio reduces manual sequencing for long narration, while the SDKs and API require basic developer knowledge to automate generation and handle low-latency streams. Fish Audio also offers a free tier for experimentation, so non-technical creators can test voice models before moving into automated workflows.

Capable platform for creators and developers, with a usage trade-off

Fish Audio is a capable option for content creators and indie developers who need realistic, low-latency voice synthesis and fine emotional control. The platform supports quick cloning from short samples and provides developer APIs for real-time use, but the credit-based consumption model can limit large-scale production unless you plan capacity in advance.
