Through cloud updates, Google Assistant has added the ability to set up Voice Match on voice enabled Sonos devices. This feature has rolled out to all households where Google Assistant is available.
Voice Match allows you to teach the Google Assistant to recognize your voice. If you have multiple people using the Google Assistant on Sonos, you can set up Voice Match to provide user-specific responses and content based on who is speaking.
This enables personalized results for the person asking Google Assistant questions. For more information about Voice Match, see the Google article here.
Here are the steps to enable Voice Match straight from the Google article linked above:
