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 enterprisegrade 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.  Frequently asked questions about voice. 

Availability 

Today, voice chat in Microsoft 365 Copilot is available in the Microsoft 365 Copilot app on mobile (iOS and Android). It will be rolling out to the desktop, web, and across the Microsoft 365 Copilot ecosystem by the end of the year. Voice in Microsoft 365 Copilot is subject to service capacity. Users will be informed in product when they are approaching service capacity for the day. In the next few months, we will bring voice capability to Copilot users without Microsoft 365 Copilot license.  

How to provide feedback 

Microsoft 365 Copilot voice features are continuously evolving. Your feedback helps improve the experience. After ending the voice chat, use the thumbs-up or thumbs-down icons next to responses to share feedback. For more information: Providing feedback about Microsoft Copilot with Microsoft 365 apps - Microsoft Support

  • Seth_Patton​ Loving the new voice feature. Looking forward to seeing it available across agents, notebooks. etc. in the near future (fingers crossed).

    A question for you: Do you know how we can check how many of our users have voice available (already rolled out to them)? We have no idea if it's rolled out to only 10% of our users or 90% of users. Some of our users have had it available (including in the web) for 6-7 weeks already, while others still don't see it. I only got it a few days ago. 

    This is critical for our comms, adoption and training, etc. If only 10% of our user base have it then we would hold back, but if we already have 90% of our users with it, we will start our comms, etc. now. We've already reached out to some other Microsoft folk, and they said there is no way to know roll out percentage but wanted to confirm.

    Note that this isn't just for voice, but all new features that roll out sporadically across our users (common problem) making it extremely difficult to manage.
