Learning to recognize speakers of a non-native language: implications for the functional organization of human auditory cortex.
Brain imaging studies of voice perception often contrast activation from vocal and verbal tasks to identify regions uniquely involved in processing voice. However, such a strategy precludes detection of the functional relationship between speech and voice perception. In a pair of experiments involving identifying voices from native and foreign language speech we show that, even after repeated exposure to the same foreign language speakers, accurate talker identification is in a large part dependent on linguistic proficiency. These results suggest that a strong integration between the brain regions implicated in voice perception and speech perception accounts for the accurate identification of talkers.
