Five-year-old articulation-disordered children, some classified as substituters and some as syllable reducers, were compared with normal child and adult controls in their production of voicing contrasts. In every comparison the substituters' performances resembled that of the normal controls, as did the syllable reducers' use of voice onset time…

There were significant differences among the groups (articulation disordered five-year-olds) classified as syllable reducers or substituters and normal children on several imitative expressive language measures, with the syllable reducers making both deletion and substitution errors and the substituters making substitution errors for functors.…

The study involving 18 four year old children was designed to determine whether or not similar processes would be identified when responses obtained through a delayed word imitation task were compared to those obtained through a delayed sentence imitation task. (SB)

Comparison of normal-speaking (N=20) and misarticulating (N=20) four- to six-year-olds and adults (N=16) revealed that adults were significantly more accurate in detecting mispronunciations than either group of children, while performance between the two groups of children was similar. Words that children found most difficult were also those on…
