Grok Voice API

xAI's Grok voice models: a speech-to-speech voice agent that listens to a recording and answers aloud in one of 28 voices, text to speech in five expressive voices, and speech to text across 25 languages. Every response reports the length of audio it was billed on, so you always know what you paid for.

You can ask Grok Voice to handle text-to-speech / voice synthesis. Powered by xAI via the Pixazo API gateway.
