Peer reviewedNittrouer, Susan; And Others – Journal of Speech and Hearing Research, 1996
Investigation into age-related differences in production of fricative-vowel syllables with 10 adults and 30 children (ages 3, 5, and 7) found that age-related differences in vocal-tract geometry didn't explain age-related differences in vowel effects on fricative noise; children master intersyllabic gestural organization prior to intrasyllabic…

Discriminability and Perceptual Weighting of Some Acoustic Cues to Speech Perception by 3-Year-Olds.
Peer reviewedNittrouer, Susan – Journal of Speech and Hearing Research, 1996
This study tested the hypothesis that there is a developmental shift in the perceptual weighting of acoustic parameters that results from experience with a native language. Comparison of 17 3-year olds and 16 adults found that age-related differences in auditory sensitivity did not fully account for age-related differences in perceptual weighting…
