Understand how your voice works with other settings
- After you teach the Google Assistant to recognize your voice, a unique voice model is created. This voice model is created on Google’s servers and then stored only on the devices where you’ve turned on Voice Match.
- When someone speaks to your device, your device sends the voice model to Google to process the query and determine if it’s you by comparing it against the voice model. Google deletes the voice model and comparison data immediately after processing.
- If Google identifies you, your device will provide your personal results.
-
Without a match, the device will treat the query as a guest query and will not provide personal results.
- If no one links their voice with Voice Match to the Google Assistant device and the person who set up the device allows personal results, anyone can access those personal results.
- After you link your voice with Voice Match, the Google Assistant will not respond with your personal results to a voice it doesn’t recognize as yours.
- A voice that sounds like yours might be able to access your personal results, such as sending an email or viewing your calendar. If you aren't comfortable with this you can turn off personal results.

- If you link your voice with Voice Match and choose specific music and video services, the Google Assistant can provide personalized music and video suggestions.
- When other people use the Google Assistant device that is linked to your voice, your media history and recommendations from these services might change.
- To stop others from using your media services, ask them to link their own music and video services.
