Audio

Flux TTS is a text-to-speech model from Deepgram for natural, expressive English speech synthesis.

It speaks with Deepgram's Flux voice catalogue of 36 English voices, which suits English voice agents, product audio and narration. Hormouz serves Flux TTS 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 "flux-alexis-en", 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.
