Yes.
If I'm yelling, likely you can get me to calm down.
If my voice drops in volume and I seem calm but what I'm saying doesn't match the apparent calmness, well..
My least likable feature.
Has come in handy a few times though.
Had to tell one guy, quietly in hopes he wouldn't hear me, "I wouldn't do that."
He stopped short and had to think about it.
He decided, and was informed, that stopping was avery good idea as was retreat.
(Boy was I ticked when he actually walked away on that one!)
