About
Copilot Audio Expression is an experimental feature within Microsoft’s Copilot Labs that transforms written text into expressive, natural-sounding voiceovers. Users can type or paste a script and choose between Emotive Mode, which allows them to select specific voice styles like Oak or expressive tones, and Story Mode, which blends multiple voices to deliver a dynamic narrative experience. The tool’s AI can reformulate content to feel engaging and nuanced, often adding subtle expressive flourishes. It currently supports English and can generate short audio clips, up to roughly a minute, in MP3 format, playable directly via the browser and downloadable without requiring a login. The interface includes an integrated web player for instant preview.

About
MAI-Voice-1 is Microsoft AI’s first highly expressive and natural speech generation model, designed to produce high-fidelity, emotionally rich audio across single- and multi-speaker scenarios with extraordinary efficiency, capable of generating a full minute of audio in under one second on a single GPU. Integrated into Copilot Daily and Podcasts, it powers a new Copilot Labs experience where users can test its expressive speech and storytelling capabilities, such as crafting “choose your own adventure” narratives or bespoke guided meditations using simple prompts. Voice is envisioned as the interface of the future for AI companions, and MAI-Voice-1 delivers this vision through its lightning-fast performance and realism, making it one of the most efficient speech systems available. Microsoft is exploring the potential of voice interfaces to create immersive, personalized AI interactions.
