A theoretical overview is presented. Phonemic information is transmitted by actions of neuro-muscular synergisms, which are organized to achieve articulatory and acoustic goals. Acoustic goals are achieved with the use of an internal model of relations between articulatory commands and the sound output. Auditory feedback is used to acquire and maintain the model, and to make situation-dependent adjustments in "postural" parameters underlying average sound level, rate and F0? which influence clarity and intelligibility. Supporting evidence concerning acoustic goals consists of findings of articulatory-to-acoustic motor equivalence. The hypothesized use of auditory feedback is illustrated by studies of patients who have experienced changes in hearing status.
