Strengths

Stateless voice cloning

Send a voice sample with the request and get that voice back. There is no voice to create, upload, or manage beforehand.

Nothing retained

The sample travels with the request and is not persisted, which keeps the consent story simple.

Natural-language style control

Speaking style is steered with open-ended instructions rather than a fixed voice list.

Multilingual dialogue

Built for expressive narration and multi-speaker dialogue across languages.

Fish Audio S2.1 Pro API — voice cloning without enrolment

S2.1 Pro is Fish Audio's production text-to-speech model and the only speech model on YepAPI that supports stateless voice cloning. Attach a short reference sample to the request and the generated speech mimics that voice.

Because cloning is stateless there is no voice to create, upload, or manage — the sample travels with the request and nothing is retained. Billing is $0.0317 per 1,000 characters, cloned or not.
