Purpose: Earlier work has established developmental benchmarks for intelligibility and articulation rate, but the intersection of these two variables, especially within individual children, has received limited attention. This study examines the interaction between intelligibility and speaking rate in typically developing children between the ages…

In this article we report on early rhythmic discrimination performance of children who participated in a longitudinal study following children from birth to their 6th year of life. Thirty-four children including 8 children with a family risk for developmental language impairment were tested on the discrimination of trochaic and iambic disyllabic…

A study analyzed frequency of occurrence of consonants, vowels, and diphthongs, syllabic structure of the words, and segmental structure of the 311 monosyllabic words of 500 words that occur most frequently in English. Three mannerisms of articulation accounted for nearly 75 percent of all consonant occurrences: stops, semi-vowels, and nasals.…

Presents evidence for four major design features of serial organization of speech arising from comparison of babbling and early speech with patterns in ten languages. Maintains that no explanation for the design features is available from Universal Grammar; except for intercyclical consonant repetition development, perceptual-motor learning seems…
