According to an exclusive scoop, Microsoft is secretly testing its first native real-time bidirectional voice model, MAI Realtime, within its MAI Playground.

The model supports full-duplex conversation (listening and speaking simultaneously) and can seamlessly switch between 17 languages. It currently offers two voices, Victoria and Grant, which are noticeably more natural than Copilot’s existing voice mode. Additionally, the model supports tool calls like web search, features configurable turn-taking mechanisms, and handles interruptions cleanly with low latency.
