Grok Voice API

xAI's Grok voice models: text to speech in five expressive voices, and speech to text across 25 languages. Transcription reports the length of the recording alongside the transcript, so you always know what you were billed for.

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