Text to Speech

Convert text to speech through the rebyte TTS endpoint. One endpoint, two providers, one voice catalog.

Requires Rebyte API auth — $AUTH_TOKEN and $API_URL are set up per the agent's system prompt.

Picking a voice

Every voice has an explicit provider prefix. Pick the voice that matches the tone you want, then compose style per its column below.

OpenAI voices (style via instructions field)

Uses gpt-audio-mini by default (fast, cheap). Pass model: "gpt-audio" for highest quality. Style is controlled via the instructions field — a natural language directive for delivery.
