Get an Alert When Something Exiting Is Happening in a Live Sports Event on TV

Why?

So you can do something else but still, catch all the exciting moments.

How?

Build into TV sets the function to monitor the human voice (of the sports commentator). When you turn this mode on the TV’s volume will go down so as not to disturb you, but when the reporter’s voice becomes excited it will automatically turn up the volume so you will not miss the exciting moment.
