Time-compressed speech discrimination in central auditory disorder: a pediatric case study

Audiological data are presented for an 11-year-old aphasic girl with confirmed left-hemisphere damage. Pure-tone audiometry, impedance measurement, and speech discrimination testing were completed. Discrimination testing included presentation of the Word Intelligibility by Picture Identification (WIPI) test at 0 and 60% time compression. Results indicated significantly poorer speech discrimination in the ear contralateral to the site of lesion at 60% time compression. This case study supports the use of time-compressed speech discrimination testing in the assessment of central auditory function of children and as a diagnostic tool for determination of site of lesion.
