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…

Mothers' speech directed to their children (N=61) from three groups --nonretarded, Down Syndrome, and language-impaired--was examined to evaluate the ways mothers adjust their speech to the child's developmental condition and linguistic competency. Mothers showed differences in mean length of utterance, use of total imperatives, evaluative…

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 investigation compared 19 adolescents' perceptions of the nonspeech personality characteristics of voice-disordered and normal-speaking children. Listeners, who rated recorded speech samples, showed a significant tendency to judge the normal speakers more positively than the voice-disordered speakers. Results suggest developmental trends in…

Eighteen cases of disintegrative psychosis (DP) were compared with 52 cases of infantile autism (IA) with speech loss and 145 IA cases without speech loss. DP cases showed clearer regression after more satisfactory development than the IA cases with speech loss, and by age seven were more severely retarded but similar in autistic symptomatology to…
