Vocal communication is multi-sensorimotor coordination within and between individuals

Abstract

Speech is an exquisitely coordinated interaction among effectors both within and between individuals. No account of human communication evolution that ignores its foundational multisensory characteristics and cooperative nature will be satisfactory. Here, we describe two additional capacities – rhythmic audiovisual speech and cooperative communication – and suggest that they may utilize the very same or similar circuits as those proposed for vocal learning.
