Communication systems generally rely on upon defined organizational schemes for signal generation and sensing. In humans, the production and perception of speech is processed by highly specialized neuroanatomical areas and processes. We have recently identified important phonetic-level features for vocal tract control during articulation in the speech motor cortex, and for spectrotemporal-phonetic features in the higher order non-primary auditory cortex (Wernicke’s area). I will discuss important similarities and differences in these representational systems with respect to feature organization and dynamics.  I will also present related work on auditory-vocal (sensorimotor) integration and transformation in speech.
