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.

About

MAI-Voice-2 is Microsoft AI’s most expressive and natural-sounding text-to-speech model to date, built for production voice experiences where fidelity, language coverage, speaker consistency, and emotional range directly shape the user experience. It is designed for assistants, customer support, audiobooks, accessibility experiences, games, podcasts, courses, simulations, and creator workflows where voice quality must sound natural, fluid, and trustworthy. It expands from English-only support to 15 languages while maintaining naturalness and expressiveness, with support for English, Italian, French, German, Hindi, Spanish, Portuguese, Korean, Chinese, Turkish, Russian, Thai, Dutch, Romanian, and Hungarian. MAI-Voice-2 offers granular emotion control through tags such as sad, whispered, and excited, along with role-based expressive speech for experiences like motivational trainers, sports commentators, or character voices.
