All 28 Grok Voices, Explained (With Samples)

xAI quietly turned Grok from a chatbot that talks into a full voice platform. The roster went from 5 voices to 28, each one cast for a specific job, and all of them speak 25+ languages natively. Helix hosts. Every voice on the roster introduces itself in its own voice. No API code is read aloud. Episode length: 6 minutes 23 seconds.
