About Fish Audio
A voice AI platform: text to speech, voice cloning and speech to text in a web app, an API and SDKs.
Fish Audio offers its features three ways: in a web app, through a REST API, and with official SDKs. The core features are text to speech, speech to text, voice cloning, voice design and realtime streaming; the web app adds a voice changer, a multi-speaker studio for long-form audio, and music and sound-effect generation. The documentation describes the current text-to-speech model as covering 83 languages with automatic language detection. For developers, the API also offers a free-of-charge model for testing, with fair-use limits. The terms prohibit crawling or scraping any page of the service, so TierDiff does not read the plan page automatically.
