There's something about a voice that's personal, not unlike the particular odor or shape of a given human body. Summoned through belly, hammered into form by the throat, given propulsion by bellows of lungs, teased into final form by tongue and lips, a vocal is a kind of audible kiss, a blurted confession, a soul-burp you really can't keep from issuing as you make your way through the material world. How helplessly candid! How appalling!
