Xai Releases No-Code Voice Agent Builder With Voice Cloning

xAI released Voice Agent Builder on July 1, 2026, a no-code tool for building voice agents using the Grok Voice Think Fast 1.0 model. It offers over 80 preset voice tones and the ability to clone a voice from two minutes of audio. The tool can integrate with external services like Notion and Gmail for automated call center tasks.

Voice Agent Builder uses the Grok Voice Think Fast 1.0 model, which xAI claims produces higher quality voice output than Google's Gemini 3.1 Flash Live or OpenAI's GPT Realtime 1.5. The tool supports Japanese conversation. Users can select from over 80 pre-built voice tones or clone a voice by providing at least two minutes of audio from the same person.

The beta release charges $0.05 per minute for API usage and issues one phone number per account. By linking the agent with external tools like Notion or Gmail, users can automate tasks such as registering reservation information in Google Calendar or processing refunds via API requests.
