Hall, D.A., Fussell, C. and Summerfield, A.Q. (2006) Reading fluent speech from talking faces: Typical brain networks and individual differences. Journal of Cognitive Neuroscience, 17 (6). pp. 939-953. ISSN 0898-929X
Listeners are able to extract important linguistic information by viewing the talker's face—a process known as “speechreading.” Previous studies of speechreading present small closed sets of simple words and their results indicate that visual speech processing engages a wide network of brain regions in the temporal, frontal, and parietal lobes that are likely to underlie multiple stages of the receptive language system. The present study further explored this network in a large group of subjects by presenting naturally spoken sentences which tap the richer complexities of visual speech processing. Four different baselines (blank screen, static face, nonlinguistic facial gurning, and auditory speech) enabled us to determine the hierarchy of neural processing involved in speechreading and to test the claim that visual input reliably accesses sound-based representations in the auditory cortex.
