When you turn on Voice Match, you can teach Google Assistant to recognize your voice so it can verify who you are before it gives you personal results. You can turn on Voice Match for a home or specific Assistant-enabled devices, like a speaker, Smart Display, or Smart Clock. Up to 6 people can turn on Voice Match for one home in the Google Home app.

Understand how your voice works with other settings
How Voice Match works- After you teach 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 turns on Voice Match for the Google Assistant device and the person who set up the device allows personal results, anyone can access those personal results.
- After you turn on Voice Match, Google Assistant won't 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, making a payment (if you’ve turned on Confirm with Voice Match), or viewing your calendar. If you aren't comfortable with this you can turn off personal results.
- If you turn on Voice Match and choose specific music and video services, Google Assistant can provide personalized music and video suggestions.
- When other people use the Google Assistant device that you’ve turned on Voice Match for, your media history and recommendations from these services might change.
- To stop others from using your media services, ask them to turn on Voice Match for the shared device and link their own music and video services.
Google may also temporarily process a model of your voice from your audio saved on Google servers to develop and improve Google's voice technologies if you:
- Turn on Voice Match, and
- Choose to save your voice and audio activity from interactions with Search, Assistant, and Maps in your Web & App Activity in your Google Account
This setting helps Google improve its audio technologies and the Google services that use them.
