Phonological processing in the auditory system: a new class of stimuli and advances in fmri techniques

Roy D. Patterson, Stefan Uppenkamp, Dennis Norris, William Marslen-Wilson, Ingrid Johnsrude, Emma Williams

It is commonly assumed that, in the cochlea and the brainstem, the auditory system processes speech sounds without differentiating them from any other sounds. At some stage, however, it must treat speech and non-speech sounds differently. In broad terms, the purpose of this paper is to consider where this speech specific processing begins in the auditory pathway. Specifically, the paper is concerned with extrapolating the concepts of an auditory model to the point where we can define matched sets of speech and non-speech sounds that can be used in a brain-imaging experiment to delimit where phonological processing of vowel sounds begins in the auditory system. Pilot results suggest that phonological processing of vowels may begin just outside auditory cortex in Brodmann area 21.
