xAI Ships a Grok Text-to-Speech API With Expressive Voice Controls

Grok's new TTS API enters a crowded field but offers fine-grained expressive controls that developers building voice-first apps will want to evaluate.

xAI released a Text-to-Speech API for Grok, adding voice synthesis to the model's existing text and vision capabilities. The API emphasizes "natural voices and expressive controls," suggesting developers can tune parameters like tone, pacing, and emphasis rather than selecting from a fixed set of voice presets.
