Earlier this month we announced voice in the Microsoft 365 Copilot mobile app. Today, we’re expanding that offering, introducing voice in Microsoft 365 Copilot app on desktop and the web, as well as in the Microsoft 365 apps, starting with Outlook, Word, and PowerPoint, and a new wake word “Hey Copilot” – an opt-in feature to start a voice chat hands-free on Windows devices.
Voice enables Microsoft 365 Copilot users to have natural, back-and-forth conversations with Copilot simply by speaking. It lets you quickly capture your ideas, whether you’re brainstorming, drafting a response, or preparing for a meeting. Just say “help me prepare for my next meeting” to get an instant response from Work IQ, grounded in your work data, context, and preferences. Copilot turns your words into polished drafts, asks clarifying questions, and suggests next steps—helping you move faster and lightening the cognitive load. We’ve observed that users interact with Copilot twice as much when using voice vs. text*, so using voice is also more engaging. Voice is transforming the way we work with Copilot—turning it into a true thought partner that helps you stay focused and productive.
You can now click “Start a new voice chat” in the Copilot input box in your favorite apps, starting with Word and PowerPoint. Brainstorm new ideas, catch up on long documents, and ask about things in the document to get related answers from all your work content. It is rolling out to the desktop and web version of Word and PowerPoint starting today.
Because on-the-go is where voice really shines, we are also bringing voice to Outlook mobile. Start by opening Copilot in Outlook mobile and tapping “Voice catch up” to launch an interactive voice experience that summarizes unread emails and guides you through actions like drafting replies, deleting, archiving and flagging – all hands-free. Early access is available for iOS and Android users via Apple’s TestFlight program and Google Play’s Beta testing program.
With voice, users can easily switch contexts and collaborate more naturally. Whether you’re driving to pick up your kids or leaning back at your desk, it’s a natural way to get ready for the workday, catch up on messages or prep for meetings. You can even start a voice chat in the Microsoft 365 Copilot mobile app, then pick it up using text when you get to your desk. Just go to Chats in the Copilot app to continue using text.
Finally, you can now start a voice chat with Copilot completely hands free by saying “Hey Copilot.” This allows you to stay focused or multitask without any interruption of switching apps and windows. This opt-in feature makes it easy to start a conversation with Copilot voice whenever the feature is enabled and your PC is unlocked. Learn more about Hey Copilot. The feature will be available through the Frontier program in the coming weeks.
Voice in Copilot is also available through Windows shortcuts. Long press the Copilot key, or for devices without a Copilot key, the Win+C shortcut to open the voice controller, a small window that stays on screen for multitasking with voice in Copilot. This shortcut eliminates the need to switch between screens, keeping users in the flow of your work as you talk through your needs. Learn more about using Windows shortcuts to activate voice in Copilot.
As we build and deploy more AI solutions, accessibility is foundational. Voice in Microsoft 365 Copilot helps make work more inclusive by supporting users with diverse needs and preferences. Using voice in Copilot on mobile, users can turn on/off closed captions and change audio speed at any time, right in the voice chat window. Learn more to get started with voice features.

*Based on internal Microsoft telemetry of work-related queries of users using Work Tab for the week of 10/27/25-11/2/25; when comparing the turn per conversation rate (as measured by the number of times a user prompts Copilot and receives a response within a single session), engagement was twice as high during the relevant time period when users used voice vs text.
