Abstract: | The assumption that listeners are unaware of the highly encoded acoustic properties which lead to phoneme identification is questioned in the present study. It was found that some subjects can make use of small differences in voice onset time when making within-category discriminations. Subjects who can use these auditory features do so both implicitly (in a phonetic match task) and deliberately (in a physical match task). Results also indicate that some type of parallel process model is needed to account for the processing of auditory and phonetic information. |
