A few years ago my wife passed away. One of the primary ways I get to hear her voice now is from her phone's (A Samsung Galaxy) recording conversations at random times and storing it as a .amr file. How do I know it was the phone and not my wife? Firstly, my wife was NOT tech savvy at all. She had to get me to fix resolution problems! Secondly, the files recorded a conversation of us in the hospital and another was of her singing with the radio while driving. These researchers simply proved that the system is smart enough to detect pre-recorded stuff versus ACTUAL RL conversation.

How about: "I dint know mice were so smart."
