Listen to my voice, you are getting verrrrrry sleepy.
Noise-Cancelling Headphones That Can Tune Out All Noise Except A Person’s Voice

Developed by researchers at the University of Washington, these noise-cancelling headphones are able to cancel all outside noise except for a person’s voice through the power of AI. You just push a button on the side of the phones to train the AI on a person’s vocal patterns, and BOOM, you won’t hear anything but them. I’m sure my girlfriend would love for me to wear a pair of these, because she’s convinced I was born with the exact opposite ability. *dodges thrown shoe* Sorry dear were you saying something?
