Abstract
The adaptive performance anatomy subserving adult human speech represents an anatomically and neurophysiologically diverse collection of tissue-muscle subsystems capable of valving and channeling the breath stream at regulated pressure levels for speech production. Complex relations in the dynamics underlying movement exist between articulators during speech production. Traumatic injury or progressive disease to brain structures involved in the selection, sequencing, and activation of orofacial, pharyngeal, laryngeal, and chest wall muscles may degrade speech kinematics and reduce intelligibility. In this article, theoretical and methodological issues pertinent to the relation between brain and speech motor behavior are highlighted from studies which use functional neuroimaging and computational modeling.
