Abstract

For many years, speech recognition threshold (SRT) testing has been used as an indicator of audiologic health. However, with changing methods and technology, test-retest reliability has not been reviewed extensively with newer digitally recorded spondaic words which meet a published criterion of listener familiarity. This study examined the test-retest reliability of 33 high frequency usage and psychometrically equated spondaic words. The American Speech-Language-Hearing Association recommended method (2-dB decrements) was used to measure the left and right SRT of 40 participants using both male and female talker recordings. For each participant, four SRTs were found during the test condition and four SRTs were found during the retest condition. All of the SRT scores were analyzed and the averaged SRT values found using a male talker recording resulted in an average retest SRT to be 1.4 dB better than the average test SRT. The averaged SRT values found using a female talker recording resulted in an averaged retest SRT to be 1.2 dB better than the averaged test SRT. The SRT scores also showed high validity when compared to each participant's pure tone average (PTA). This study additionally found no significant interaction in using a male versus a female talker when using digitally recorded and psychometrically equated spondaic words.
