ABSTRACT
We draw on neurophonetics to review and discuss speech production from a bottom up approach by considering the constraints biology places on the vocal tract and motor system. We introduce a tripartite model to discuss both typical and atypical speech production. We then delineate the neuroanatomic basis of speech from motor executive processes to cortical auditory-somatosensory-motor integration focusing on the emergence of phonological structure. The transitions between the three processing levels in the tripartite model are continuous; the coherent architecture of this connected system suggests there is no room for a strict demarcation between linguistic and motor speech processing.
