Contrastive stress production by children with cochlear implants: Accuracy and acoustic characteristics.

The aim of this study was to examine the abilities of eight early-implanted children with cochlear implants (mean age 7.1 years) to produce contrastive stress and to compare their use of amplitude, duration, and fundamental frequency, to an age-matched group of children with typical hearing (mean age 6.11 years). A set of 16 utterances were elicited in which the child was required to stress either an adjective or noun in a short phrase. Although both groups of children produced similar proportions of utterances with stress patterns perceived by hearing listeners as accurate, they employed different strategies for achieving contrastive stress.
