Acoustic analyses, along with perceptual ratings, measured the extent to which preschoolers imitated three modeled intonation contours (declarative, interrogative, and monotone). Results indicated that five-year-old children imitated modeled contours more frequently than did three-year-old children, with between-group differences largely because…

Localization acuity was examined by determining the smallest sound shift off midline and along the horizontal axis that infants 6-18 months could reliably discriminate. As their age increased, infants demonstrated a finer partitioning of auditory space along the horizontal axis. (PCB)

This study found that 5 7-year-old and 4 10-year-old prelingually hearing-impaired children displayed evidence of anticipatory coarticulation based on temporal and spectral cues, but they did so to a lesser degree than normally hearing children. (Author/JDD)

Measures of both temporal and spectral parameters were computed to determine the extent of perseveratory coarticulation in the vowel-consonant syllables produced by 7- and 10-year-old children (n=9). Profoundly hearing-impaired speakers exhibited measurable but smaller effects of perseveratory coarticulation relative to the normally hearing…

Acoustic and video data tracing the development of intrasyllabic coarticulation suggest that young children (n=30; ages three, five, and eight) and adults (n=10) produce similar patterns of anticipatory coarticulation, and perceptual data indicate that coarticulatory cues in the speech of three year olds are less perceptible than those of the…

This study examined the interaction of acoustic-phonetic information with higher-level linguistic contextual information during the real-time speech perception process in child, young adult, and older adult listeners. Findings indicated that target word predictability influenced the timing and nature of the real-time recognition process, including…
