I can not stand loud talkers and lip smackers.

Just say, "Honey, i hear you. You have my attention." And then just go back to what you were doing. If you hear her tone go up sharply, it's probably a question - say "Maybe", or shake your head northeast to southwest, or roll it in a circle. If her tone goes down, it's most likely a statement. Just nod your head.

Vwala!
