I'm convinced my Android phone listens to me and then Google suggests links, ads, etc. directly tied to my conversation.

I have had things pop up in my suggested searches that are either people's names from 20+ years ago that I've only said out loud, or products. I've never searched for them, but there they are. I told this to a friend of mine last week. He initially scoffed. Then it happened to him. Keep in mind as crazy as this sounds, your smart phone is perfectly capable of doing a vocal google search already. I'm merely suggesting it's never truly turned off.
