Auditory-Visual Speech Processing (AVSP) 2010
Hakone, Kanagawa, Japan
Both auditory and visual information plays an important role for audiovisual speech perception during face-to-face communication. Several behavioral studies have shown that native English speakers and native Japanese speakers behaved differently in audiovisual speech perception. We hypothesized that there would be differences in neural processing between native English speakers and native Japanese speakers. Twenty-two English language speakers and 22 Japanese speakers watched talkers face and listened to talkers speaking during functional magnetic resonance imaging (fMRI) scanning. The lateral occipitotemporal gyrus was associated with visual domain of audiovisual speech perception in native Japanese speakers, but not in native English speakers, suggesting that language environment affects neural processes for audiovisual speech perception.
