Abstract: The purpose of this study was to devise and test a methodology to investigate cortical activity during speech perception and production that eliminates some of the confounding variables that have existed in previous research, such as the variability of stimuli employed across conditions and the role of muscle artifacts; and to clarify the role of auditory feedback in speech. Evoked potentials to the speech stimulus /ba/ were obtained while the subject was hearing and speaking /ba/ with and without immediate air conducted feedback, as well as while hearing /ba/ 0.6 sec. after each of these three conditions. Twelve adults were determined to have dominant left hemispheres through a series of seven hemispheric dominance tests. None had a history of a hearing deficiency or indicated a hearing loss during the practice session. Monopolar recordings were made from the left and right frontal areas corresponding to Broca's area on the left and the left and right temporoparietal areas posterior to the termination of the Sylvian fissure, with a linked earlobe reference.
