Audio

S1 is a multilingual text-to-speech model from Fish Audio, suited to voice applications that need broad emotional expression.

It has no fixed voice list: speaking style and emotion are set with controls written into the text. S1 uses parenthetical controls, such as an emotion in brackets before a sentence. Hormouz serves Fish Audio S1 on two endpoints: the OpenAI-compatible /v1/audio/speech, which returns the audio in the same response, and /v1/predictions for background jobs. Set response_format to mp3 or pcm.

Billing is per UTF-8 byte of input text (a Persian character counts as two bytes); the current rate is in the price table on this page. Hormouz provides stable access to it from inside Iran, with no foreign credit card or circumvention tooling required.
