When a Nest Mini hears you but does not respond, or does not hear you at all, Google's help and owners point to a short list. First check the microphone switch on the side: if the lights are orange, the mic is off and nothing you say is heard. Then check that Hey Google is on for this speaker in the Google Home app and that its sensitivity is not set too low. Voice Match may need retraining if the speaker used to recognize you and now does not, and owners fixed this by deleting the old voice model and recording it again.
A noisy room, a speaker placed against a wall, or music playing from the same speaker also makes recognition poor. Account mismatches cause responses of I can't help with that, so make sure the speaker and your phone use the same Google account. If the Mini responds to your phone's Assistant but not to the speaker, the speaker's Hey Google setting is the one to check, since phone and speaker settings are separate. If the speaker wakes but cannot play music, check the linked music service in the app.

Model-specific
What is true of this model and not of its siblings
- Switch first
- The physical mic switch is the most common reason for silence.
- Retraining
- Deleting and recording Voice Match again fixes many recognition problems.
- Phone versus speaker
- Assistant settings on the phone do not change the speaker.
- Far-field microphones
- The Mini listens across a room, so competing sounds matter.
- Music links
- A Mini that hears you but cannot play music has an account or service link problem.
Stop boundary
When this stops being a self-service repair
- !If the speaker never responds with the mic on and settings correct, factory reset and set it up again
- !If the problem began after an update, report it to Google Nest support
- !A speaker whose lights never respond may be faulty
