View guide →Fish Speech — Fish Audio's expressive open text-to-speech and voice cloning: SOTA-quality TTS you can self-host, under the Fish Audio Community License (check terms)
Fish Speech is an open-source audio project by fishaudio (fishaudio/fish-speech on GitHub). It has 33,289 GitHub stars and 2,891 forks, is released under the Custom (check repo) license, and was last updated on GitHub on 14 October 2026.
Follow the official installation guide (linked from the README at speech.fish.audio/install): environment setup and weight downloads, or use the Docker deployment the repo ships.
Get the current Fish Speech weights from the project Hugging Face organisation (fishaudio) as the install guide directs.
Run inference through the WebUI for interactive cloning/TTS, the command line for batches, or the API server when another app should call it.
Natural, expressive synthesis with voice cloning from reference audio — the project headline capability.
Three ways in: a browser UI for people, a CLI for scripts, and an API server for products.
The repo ships Dockerfiles and compose files for a self-hosted deployment without hand-building the environment.
The S2 model line and Hugging Face releases are current — the repo was pushed in October 2026 and its licence was refreshed the same month.
The README routes all setup through the official docs: environment, weights, Docker.
https://speech.fish.audio/install/The repo ships compose files (compose.yml and variants) for the container deployment described in the docs.
git clone https://github.com/fishaudio/fish-speech.git
cd fish-speechCLI, API server and WebUI inference are documented step by step here.
https://speech.fish.audio/inference/Fish Audio (fishaudio on GitHub), the team behind the fish.audio platform; this repo is their open TTS system.
For research and non-commercial use, yes, free of charge under the Fish Audio Community License. Limited commercial use is allowed below a revenue threshold; larger commercial or hosted-service use needs a separate licence from Fish Audio — read the LICENSE file in the repo.
Only clone voices you have the right to use — your own or with clear permission. The project disclaims responsibility for illegal usage, and consent and local law are on the user.
Against Chatterbox (also new on LibreAI this week), Fish Speech is the heavier, hosted-platform-grade system with a custom community licence; Chatterbox is MIT-licensed and simpler to embed. Against XTTS-style research models, Fish Speech is the more productised, actively released option.
Follow the install guide at speech.fish.audio/install (or the Docker route), download the weights from Hugging Face, then generate from the WebUI.
