What is Fish Audio?

Fish Audio is a voice platform built on the Fish Speech research models: expressive text-to-speech, quick voice cloning and speech-to-text, sold both as a creator app and as one of the cheapest voice APIs on the market. Its S2.1 Pro model is the recommended default, with an emotion-directed Drama 3 model above it, and the underlying models are published as open weights under a community licence.

The free plan includes about 8,000 credits a month (roughly 7 minutes of speech) for personal use. Plus is $15/mo (about 200 minutes, with commercial rights and a professional clone slot) and Pro is $100/mo (about 1,620 minutes, team seats). Developers can skip subscriptions entirely: the API charges $15 per million characters of text — around 12 hours of speech — pay as you go.

Who Fish Audio Is Best For

Best for: Fish Audio is a strong fit for podcasters, voice artists, and audio producers: Among the cheapest quality voice APIs available; free tier and free API model make testing painless. The free plan makes it easy to try on real work before paying anything.

Not ideal for: Less suited to users who will hit its limits head-on: free plan is personal use only — commercial rights need a paid plan; credit maths (credits per minute) takes a moment to learn.
