Familiar voice recognition appeared on the earth 250 million years ago with the advent of frogs. Interestingly, air breathing and vocalization coemerged in the amphibian, as they do as first gesture in the human newborn, suggesting that the larynx was designed to serve these two functions with equal commitment. Establishing a repertory of familiar voices plays a crucial role across biological species, enabling identification of family, friend, and foe in the distance and at night. All voices, familiar and unfamiliar, transmit a cornucopia of data about the speaker, a capability which began simply and has flourished prodigiously in the human to include gender, age, size, sexual preference, socioeconomic and geographical background, mood, emotion, linguistic meanings, pragmatic communication, attitude, and psychiatric state. Considering that vocal information draws on an immense range of human behaviour, one can conclude that it takes a whole brain to produce and perceive a voice pattern.
