Listen for “Hey Siri” typically does not work as expected when your device is locked



When attempting to use “Hey Siri” when your device is locked, you will typically find that the device will wake but there will be no indication that Siri has been activated and any command will not be actioned or receive a response.

Steps to reproduce

  1. Ensure that Listen for “Hey Siri” is enabled.
  2. Ensure that VoiceOver is enabled.
  3. Lock your device.
  4. Say “Hey Siri” followed by a question or command, such as “what time is it?” Or “play my favourite music”

In the case of the above examples, you would expect Siri to announce the time or to start music playback.

What actually happens is that your device will wake, but there will be no response from Siri.

Note that “Hey Siri” works as expected when your device is unlocked. It also works as expected when your device is locked and VoiceOver is disabled.

My oldest son, who is not a VoiceOver user, has encountered this problem after updating to IOS 15 on his iPhone 11, so this may not necessarily be a strictly VO issue. In his case, I believe turning the phone off and back on solved the problem.
