Google Home uses Voice Match to determine who is speaking and to provide personalized results.

My Google Home knows me as a friend – maybe even better. He knows my favorite music, my grocery list, and what my schedule looks like for ages. But the one thing that ties all of these details together is perhaps the most personal thing Google Home knows about me: the sound of my voice. Google Home uses what’s called Voice Match to recognize who’s talking to it and to deliver personalized results, and if you’re not using it yet, you should – especially if you live with others.
Adopt a fair voice for Google Home
Many times family members look strangely alike – siblings, in particular. If this is the case, and Google Home cannot tell two people apart, there is a clear way to tell them apart: adopt a “smart speaker” voice that you only use when talking to Google Home.
To test this, I used one of my Google accounts not associated with Google Home to add a household member and set up Voice Match. Since my main account had already configured Voice Match with my real voice, I configured my second using a falsetto.
Create a dummy account
Suppose you have Voice Match enabled, and since you listen to a lot of music with your smart speaker, you have linked your Spotify account as well. If someone else requests music and they’ve enabled Voice Match and they’ve linked their own Spotify account, Google Home will play from their account, but only if all of these conditions are met.
But what about people who don’t have a Voice Match profile or who haven’t connected their own streaming services? In these cases, Google Home defaults to accounts owned by the first person to set up Voice Match. That might not be much of a problem if you don’t rely on Spotify’s recommendation engine to discover new music, but if you do (and most people I know) then the fact that other people using your account will include their music tastes in Spotify’s algorithm.
How to set up a new Voice Match profile or retrain the one you already have:
Tap Assistant settings and then tap Assistant in the menu bar at the top.
Tap Voice Match then configure a new profile or retrain your current profile.
Follow the prompts and read whatever the app tells you to say in the voice you want Google Home to associate with your account.
