Auditory Processing in Specific Language Impairment (SLI): Relations With the Perception of Lexical and Phrasal Stress

The authors investigated whether impaired acoustic processing is a factor in developmental language disorders. The amplitude envelope of the speech signal is known to be important in language processing, and the authors examined whether impaired perception of amplitude envelope rise time is related to impaired perception of lexical and phrasal stress in children with specific language impairment (SLI). The SLI group had difficulties with both acoustic and stress perception tasks. The authors reported the data suggest that poor sensitivity to amplitude rise time and sound frequency significantly contributes to the stress perception skills of children with SLI. Other cognitive factors such as phonological memory are also implicated.
