It offers seven preset voices, such as tara, leah and dan, and suits narration, voice assistants and interactive applications. Hormouz serves Orpheus 3B on two endpoints: the OpenAI-compatible /v1/audio/speech, which returns the audio in the same response, and /v1/predictions for background jobs. Set voice to one of the model's own voices, for example "tara", and response_format to mp3 or pcm.

Billing is per character of input text; the current rate is in the price table on this page, and you pay only for what you use. Hormouz provides stable access to it from inside Iran, with no foreign credit card or circumvention tooling required.
