PHOENIX -- While the exact numbers vary, experts agree that a large portion of what we say doesn't come from our mouths. It's comes from non-verbal communication -- body language, gestures, facial expressions, eye contact, blinking, voice quality and speaking style.
While body position and voice tone are telling, the key often is in the nuances of expression. The subtle variations in facial expressions -- many of which are uncontrollable barely discernible movements displayed for the merest fraction of a second -- can make a world of difference in the message that's conveyed.
