Meta brings voice calls and expressive avatars to Muse
The update is available only in the US, with voice conversations also planned for Meta’s AI glasses and Muse Charm device.

Meta’s personal AI agent Muse now supports spoken conversations and an animated character that responds during calls. The company has made the features available in the US through its phone, web and Mac apps.
According to Meta, callers can interrupt the agent and receive an immediate response, while Muse continues handling other tasks in the background. Calls begin through a phone icon at the app’s upper right.
The avatar uses gestures and facial expressions to reflect the conversation’s tone, including reactions before a user finishes speaking. Users can hide it for an audio-only experience, display it beside the conversation or expand it to fill the screen. Hundreds of voice options are available, and users can change voices during a call.
Meta Superintelligence Labs developed the Muse Realtime Avatar model behind the animated characters. Meta demonstrated the technology at its Connect conference in September, where it also said users would be able to describe the voice they wanted, including its speed or accent.
Meta said its own raters favored its avatars over offerings from Runway and HeyGen. The company has also cautioned that some demonstrations do not represent the avatars currently offered in the app.
Muse launched in September and uses the Muse Spark model family introduced in April. Its existing functions include retailer shopping, email sending and Mac app control. Meta says voice conversations will also reach its AI glasses and Muse Charm, a clip-on device shown at Connect, but has provided no launch date for either.
