Introducing voice in Microsoft 365 Copilot! Now you can talk to Copilot, interrupt naturally, and get real-time spoken responses grounded in your work and web data—just click “Start a new voice chat” in the input box. Because work doesn’t stop at your desk, voice helps you stay productive anywhere—hands-free, on the go, or while multitasking. Available today in the Microsoft 365 Copilot mobile app for Copilot-licensed users, with desktop and web coming soon.
Voice lets you quickly capture your ideas in a natural way, whether you’re preparing for a meeting or your day, brainstorming some ideas or drafting a response. It’s especially powerful on the go, like during a walk or commute. Copilot can also turn your words into polished drafts, ask clarifying questions, and suggest next steps— helping you move faster and lighten the cognitive load.
How voice in Copilot works
Users can speak freely during voice chats and interrupt Copilot at any time. When interrupted, Copilot will stop speaking, listen to the new input, and respond accordingly. Users can adjust how Copilot speaks by just asking it to make it faster, slower, louder, more energetic. To mute, select the “Mute” button. To end the conversation, select “End voice chat” and Copilot will leave the voice chat and stop listening. For the best response quality, users are encouraged to reduce background noise during active voice chats. Chat transcripts are saved under Conversations in Copilot Chat, so users can resume the conversation when needed.
Security and privacy
Voice in Microsoft 365 Copilot adheres to the same enterprise‑grade commitments to data security and privacy that Copilot takes with text interactions. Text transcripts from voice chats are stored and managed like regular Copilot conversations, so your existing retention, eDiscovery, and audit policies apply to the transcript content. No user or Copilot audio is stored. Microsoft applies additional checks for intellectual property, jailbreak attempts, harmful content, and other risks in alignment with our AI Safety practices.
