Overview

Everything Fish Audio can do — and how to build with it

Fish Audio is a voice AI platform. Every core feature is available three ways: in the web app (no code), through the REST API, and via the official SDK.

Core features

Text to Speech

Convert text into lifelike speech with the s2-pro and s1 models.

Speech to Text

Transcribe audio to text with per-segment timestamps.

Voice Cloning

Clone a voice instantly from a clip, or train a persistent model.

Realtime Streaming

Stream audio as it generates — for voice agents and live apps.

Manage Voices

List, inspect, update, and delete your voice models.

Also in the web app

These run in the browser, no code required — see the Platform guide.

Voice Changer

Transform existing audio into a different voice.

Story Studio

Produce multi-speaker, long-form audio — audiobooks and narration.

Music & Sound Effects

Generate music and cinematic sound effects from a prompt.

Audio Separation

Split audio into stems, and related processing utilities.

Models

Two text-to-speech models power most capabilities:

• s2-pro — the default, highest-quality model, with multi-speaker and natural-language expression control.
• s1 — the previous generation, with (parenthesis) emotion tags.

See Models Overview and Choosing a Model for the full lineup, languages, and limits.
