You can find all of your Google activity, from Google Maps navigation to search engine queries, in the My Activity section of your Google account. You can read a list in the Google Home app or actually listen to your own voice search history (if it has indeed been recorded). Fortunately, you can easily purge your account of all these recordings.
How to delete your Google Assistant voice recordings on your PC
Go to myactivity.google.com on desktop. If you have multiple Gmail accounts, make sure you’re signed into the one associated with your Google Home device.
Click Web & App Activity.
Choose Manage Activity.
Click Filter by date & product.
Check Voice and Audio in the list of Google Products and click Apply.
From there, you can view a chronological list of all the commands you’ve given your device. You can manually select the X to delete commands one by one, or you can set a date range to clear a larger set of commands.
How to delete your Google Assistant voice recordings on your phone
Unfortunately, you can’t filter by date and product in the Google Home app yet. You can only filter by date, so you either have to delete commands one at a time, delete everything or your web activity gets lumped in. It works on mobile browsers though.
Go to myactivity.google.com on mobile browser. If you have multiple Gmail accounts, make sure you’re signed into the one associated with your Google Home device.
Select Filter by date & product.
Scroll down and select Voice & Audio.
From here, it’ll work the same as if you were deleting recordings on desktop.
