| Abstract | Determined whether the perceived onset of a word (P-center) was sensitive to the phonetic identity of the prevocalic segments of a syllable using 3 Subjects in 4 experiments. It was found that phonetic judgments were categorical while P-center judgments were continuous. Results demonstrate that P-center location is not determined by the phonetic identity of syllable initial consonants nor by the rise time or the amplitude envelope of the signal as P. Howell (1984) has argued. It is suggested that, instead, a combination of the duration of the prevocalic consonant and the duration of the syllable rhyme is at work. Both the phonetic structure of a syllable and the particular acoustic realizations of its structure affect the location of the P-center. |
