The tech giant is currently letting Windows Insiders with the updated Copilot Voice app try out the new feature, which follows the lead of the likes of Siri, Google and Alexa.

In a blog post, the team said: "To get started, enable 'Hey, Copilot' in the Settings of your Copilot app, then simply ask a question starting with 'Hey, Copilot…'

"You’ll see the Copilot microphone appear on your screen, along with a chime to indicate that Coplot is listening.

"To end a conversation, tap ‘X’ or Copilot will end the call automatically after a few seconds of no interaction.

"You will hear a chime confirming that the conversation has ended."

Microsft noted that once the feature is enabled, you can ask a question with the 'Hey Copilot' prompt "anytime your PC is unlocked.

They continued: "Anytime the wake word is detected you will see the Copilot Voice Floating UI appear on the bottom of your screen and either hear a small chime, or a voice greeting or response from Copilot."

The team clarified that if you see the interface, that means "you are in a conversation with Copilot Voice".

Addressing potential privacy concerns about data, voice or recordings being sent to the cloud, they insisted that isn't the case.

They explained: "When ‘Hey Copilot’ is enabled, Copilot uses the microphone with an on-device wake word spotter that only detects the ‘Hey Copilot’ phrase.

"The wake word spotter uses an on-device 10 second audio buffer in memory. This audio buffer is never recorded or stored locally.

"When the wake word is detected, the Copilot Voice Floating UI will appear and begin to establish a Copilot Voice conversation.

"In parallel, the audio buffer will send audio from when 'Hey Copilot' was detected to the cloud so it can be used to help answer the question you asked."
