They like it, but it really doesn't make much of a difference. I've got quite a deep voice (like, a little deeper than Morgan Freeman), and I've never really had a comment on it (from non-family females, anyway).
I got a deep voice. I called my wife at work a few years ago and another lady answered. I heard the lady tell my wife that there was a sexy voiced man asking for her. My wife answered the phone all excited until she realized that it was me. LOL
