A recent article on Hacker News pointed out a lesser known aspect of Google search, how it keeps recordings of all of your Google Voice searches. The article also explains how you can find these buried away in your account settings and how to delete them. Please Log In to view this link! This wasn't really much of a surprise really, regardless of how they tried to keep it on the down low for the most part. A couple years ago, it was revealed that Google had filed for a patent to listen for ambient noise via a computer or mobile device's microphone, to influence the search results it would return for a user. If you haven't already, now would be a really good time to go through all the hidden settings for your Google account, and disable what you no longer wish them to track about you.
