Today, we're excited to announce a partnership with Vapi to serve as the default engine for Vapi's 12 core voices, bringing a new level of naturalness and emotional range to the 2.5M+ voice agents built on the Vapi platform.
Quality That Wins
Vapi conducted an independent, blind evaluation comparing Grok Voice against other providers. In their head-to-head arena, Grok took the #1 spot.
The results aligned with what we've seen. In a side-by-side poll on X, over 4,500 users were split 50/50 when guessing which voice was the Grok AI clone versus the human original.
Decide for Yourself
Don't take our word for it. Listen to how this new Grok-powered voice compares to the previous generation.

Okay,so I'm pulling up your account right now,and it looks like—oh,wait,that's not the right one.
What This Means for Vapi Developers
If you're already building on Vapi, your agents can now use Grok to power Vapi's text-to-speech. Select it from the dropdown and take it for a spin. You'll immediately get more natural, emotionally resonant conversations.
Additionally, Grok Speech-to-Text and Text-to-Speech are now available in the Vapi Dashboard.
New voices and advanced customization options (including custom voice cloning) are also available through the Grok Voice API for teams that want to integrate it directly in use cases like narration, podcasts, advertising, voiceover, and more.
Ready To Start Building?
Head over to your Vapi dashboard — the new default voices are live now. Or try Grok Voice directly via the API if you're building outside of Vapi.
We're thrilled to be powering the voice layer for one of the leading voice AI platforms and can't wait to see what you build with it.
