| Abstract | An examination of the vowel information present in initial & final regions of /b/-vowel-/b/ syllables was conducted with 2 experiments (total = 69). Vowels were identified for unedited syllables spoken by a M & a F, for the initial 20% of the syllables, for the final 20% of the syllables, for the initial & final 20% of the syllables combined & separated by a 60% silent gap, & for the initial & final 20% of the syllables interchanged across talkers & separated by a 60% silent gap. Results indicate (1) that there is considerable vowel information present in the dynamic regions at the beginnings & endings of syllables; (2) that the information is, to a large extent, carried relationally by those regions; (3) that the information is talker-independent in form; & (4) that the information is complementary to, & distinct from, formant frequency information present in a syllable's center. An experiment assessing the perceived source(s) of these stimuli suggests that source perception is influenced by as yet unspecified acoustic modulations defined at the syllable level. |
