| Abstract | Applied the distinction between auditory and phonetic processes in speech perception in the design and analysis of an experiment. Earlier studies had shown that dichotically presented stop consonants are more often identified correctly when they share place of production (e.g., /ba-pa/) or voicing (e.g., /ba-da/) than when neither feature is shared (e.g., /ba-ta/). The present experiment tested whether the effect has an auditory or phonetic basis. Increments in performance due to feature-sharing were compared for synthetic stop-vowel syllables in which formant transitions were the sole cues to place of production under 2 experimental conditions: when the vowel was the same for both syllables in a dichotic pair, as in earlier studies, and when the vowels differed. Since the increment in performance due to sharing place was not diminished when vowels differed (i.e., when formant transitions did not coincide), it is concluded that the effect has a phonetic rather than an auditory basis. Right ear advantages were also measured and were found to interact with both place of production and vowel conditions. The 2 sets of results jointly suggest that inhibition of the ipsilateral signal in the perception of dichotically presented speech occurs during phonetic analysis. |
