| summary | The relationship between speech perception and production and their underlying representations lies at the core of the field of speech communication, and is crucial to the understanding of the interface between phonetics and phonology. While most work in this area has focused on contributing motor, auditory, and to some extent visual processes, few studies have examined somatosensory component. The major themes of my research have attempted to address this deficit, with emphasis on orofacial somatosensory function in speech production and perception. A novel orofacial skin stretch perturbation paradigm has been used in a series of studies to probe the orofacial somatosensory system while excluding involvement of the motor system. By observing behavioral change and electroencephalographic activity in response to the perturbation in speech motor learning and perception, we found a significant role of orofacial cutaneous inputs in speech production and moreover its somatosensory inputs related to speaking motion interact with speech sound processing in both behavioral and neurophysiological level. The result suggests somatosensory system may play an important role in the link between speech perception and production. |
