The production of contrastive stress was studied in normal-hearing and severely and profoundly hearing-impaired children. A picture description task was used to elicit utterances. Contrastive stress was assigned by changing one element in the second and third pictures in sets of three pictures. Stress production was assessed perceptually and acoustically. The normal-hearing and the severely hearing-impaired children were judged to have consistently stressed the element that was changed in the pictures. Some of the profoundly hearing-impaired subjects were judged to have stressed the changed element more often than chance but some did not perform above chance. Acoustic measurements indicated that only the normal-hearing speakers significantly varied both duration and fundamental frequency when stressing words while some of the hearing-impaired children varied only duration. These findings were interpreted as indicating that profoundly hearing-impaired speakers had difficulty producing recognizable contrastive stress and showed deviations in the duration and fundamental frequency of their utterances.
