Time-compressed speech discrimination in children and its relationship to articulation.

The Word Intelligibility by Picture Identification (WIPI) Test of Speech Discrimination was time compressed at 0, 30, and 60% and administered to 48 normal-hearing children. The children, all between the ages of 5 years, 6 months and six years, 7 months of age, were equally divided into three groups on the basis of articulation ability. Significant effects were found for test groups and levels of time compression, with differences increasing as time compression increased. The implication is that children with multiple articulation errors demonstrate a developmental lag in the ability to process time-compressed speech. Time-compressed speech may be a useful tool in the study of auditory perception in children.

Synthetic sentence identification as a function of the age of the listener.

Synthetic sentences with ipsilateral competing message (SSI-ICM) were presented to 40 normal-hearing listeners in four distinct age ranges at five message-to-competition ratios (MCR). Children, ages 10-12 years and adults ages 20-29, 40-49, and over 60 years were presented SSI-ICM at MCR's of 20, 0, -10, -20, and -30 dB. Discrimination scores decreased with increasing MCR for all groups. Discrimination scores demonstrated a curvilin-ear function with a maximum in the 20-29 age group. The age effect was most pronounced for the more difficult MCR's. The results are discussed relative to the clinical use of the SSI-ICM and the implications for clinical speech discrimination testing in general.
