Microsoft 365 Copilot: “Hey Copilot” to start voice in Copilot on Windows devices
Starting late November 2025, Microsoft 365 Copilot on Windows will support hands-free voice activation by saying “Hey Copilot,” off by default and enabled in settings. It operates locally without recording audio, supports English activation, and requires manual muting or dismissal to end conversations.
“Hey Copilot” to start voice in Copilot on Windows devices
Introduction
Starting late November 2025, we’re introducing a new hands-free way to activate voice in Microsoft 365 Copilot on Windows devices. Users will be able to start a voice chat with Copilot by saying “Hey Copilot”. To end the conversation, users need to press the “Dismiss/X” button in the voice chat controls. In the future, users will be able to end the chat with a voice command. This allows users to stay in the flow of work, without switching apps or windows, while getting assistance from Copilot using voice.
Important: The “Hey Copilot” feature is off by default.
Users can manually enable the feature by going to Settings > Quick view in the Microsoft 365 Copilot app and turning on the Listen for “Hey Copilot” toggle. When on, this capability operates locally on the device and only activates by “hearing” the trigger word “Hey Copilot” without recording or storing any conversation. Text transcripts from voice conversations with Copilot are stored and managed in the same way as text conversations in the Microsoft 365 Copilot app. No user or Copilot audio is stored. For more information about data retention for Copilot, see Data, Privacy, and Security for Microsoft 365 Copilot.
