Microsoft AI released MAI-Transcribe-2-Streaming, its first streaming speech-to-text model, on October 1, 2026. The model reached #1 of 38 for final transcript accuracy at 2.5% WER with 0.13s time after speech ended. Streaming outputs first partials in about 100ms and revises them as context arrives, enabling agents to act mid-sentence while dictation is ongoing.
