What can one tell from a person's voice (on the phone)?

I worked at a place that had a woman named Carol Ann that dealt with customers on the phone. Her voice was like a teenage girls, very "sweet" and a little bit high pitched. You would expect her to be some cute little girl. She was pretty good with the customers and they all liked her.

Once in a while, a customer would come in for something and say "I just have to meet Carol Ann"... So... We would take them to her office and suddenly their fantasy of what she looked like was dashed on the rocks.. Carol Ann was only 5' tall, and she weighed about 250 lbs. She often drove her full dress Harley to work too. Not what you would call a pretty woman either.

She quit working there... Her and her husband moved to Florida and they went to work for Disneyworld.
