Accidental voice command activation could mean Google is storing speech that you didn't intend it to.

Android devices may be hearing more than you think, and they may be keeping track of it all somewhere you've never really looked.

Through the Google voice search feature, users on all platforms that have a Google app have been able to conduct their internet explorations verbally for some time. It's an easy to use feature, and one that helps you with hands-free searching.

But most people probably don't know that Google is keeping track of these searches too... and in a different location from the rest of your search history.
