Influence of Initial and Final Consonants on Vowel Duration in CVC Syllables.
Naeser, Margaret A.
This study investigates the influence of initial and final consonants /p, b, s, z/ on the duration of four vowels /I, i, u, ae/ in 64 CVC syllables uttered by eight speakers of English from the same dialect area. The CVC stimuli were presented to the subjects in a frame sentence from a master tape. Subjects repeated each sentence immediately after hearing it from the tape. Vowel duration measurements for the 512 utterances were taken from duplex oscillograms produced at 20 cm./sec. A repeated measures analysis of variance was performed on the vowel duration measurements (initial voicing by initial manner by final voicing by final manner by vowel). Vowel duration was increased significantly (1) if the initial consonant was voiced rather than voiceless, (2) if the final consonant was a fricative rather than a stop, (3) if the final consonant was voiced rather than voiceless. The vowels showed significantly different mean vowel durations, /I/ being shortest and /ae/ being longest. (Author/AMM)
