Microsoft is rolling out a hands-free feature for its Copilot Voice application on Windows 11, allowing users to start conversations by saying “Hey Copilot!” Beta testers, known as Windows Insiders, can activate this feature within the updated app. Users need to enable the feature to respond to the wake word, and the rollout is gradual, with availability to testers worldwide who have set their display language to English. Eligibility requires the Copilot app version to be 1.25051.10.0 or higher. Once activated, a microphone icon will appear, and the feature uses an on-device wake word spotter with a 10-second audio buffer, ensuring audio clips are not sent to the cloud or stored locally. Full functionality requires online access for cloud processing.
