On the Regulation of Consonant Duration in the Speech Perception and Production of Adults and 5 to 7 Year Old Children.
Hawkins, Sarah; Tatham, M. A. A.
The perception of duration in consonant segments is compared with their produced durations, and adults' and children's performance in this respect are compared. The temporal organization imposed by adults on initial consonant clusters was often not imposed by children from four to eight years of age, even though the cluster was produced "correctly." An experiment was designed to help determine the perceptual importance of the differences between adults' and children's productions, and to indicate some possible causes of the differences. The research questions were: (1) What are the just noticeable differences (JNDs) for durations of consonants in clusters? (2) Are the characteristic durations of clustered consonants in the speech of adults also preferred by them in their perception of speech? (3) Do the immature patterns in children's production of consonant clusters stem from muscular constraints or from an immaturity of the central timing regulator? Tables include an analysis of (1) variance for the variances of stimuli, (2) mean duration and standard deviations in perception and production of /s/ and /t/ by children and adults, and (3) Mann-Whitney U tests on adult and child voice stimuli. Spectrograms of the synthetic speech of the experiments are presented. (JK)
