Children's perception of time-compressed speech on two measures of speech discrimination.
Time-compressed versions of the WIPI and PB-K 50 speech discrimination measures were presented at two sensation levels to 60 children divided into three age-groups of 20 each. Results showed that average intelligibility scores increased as a function of increasing age and sensation level and decreased with increasing amounts of time compression. The PB-K 50 measure was found to be more difficult than the WIPI for each age-group under each condition of time compression and sensation level. The several factors under study were found to interact. The results are discussed relative to open- versus closed-message set response tasks and the implications for audiological diagnoses of children with central auditory processing problems.
