Grok's @bot can now place phone calls in a voice that sounds like the user
The feature moves AI agents from writing text in a chat window to carrying out a routine voice task. The voice technology behind it is supplied by HeyGen, which positions it as its highest-quality voice model.
How the feature works

STEP 2

STEP 3
