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.

The purpose of this study was to determine the test-retest reliability of digitally recorded word recognition materials. Word recognition testing is included in a complete audiological evaluation to measure an individual's ability to discriminate what they hear. A phonetically balanced list of 50 monosyllabic words was presented to each participant at four different sensation levels (SL) using the American Speech Language Hearing Association recommended protocol for word recognition score testing. Each participant took a 10 minute break before the test was readministered. Participants included 40 subjects with varying levels of hearing loss, from normal hearing to severe hearing loss. The test and retest scores of all participants were analyzed to estimate the test-retest reliability to be .65 at 10 dB SL, .87 at 20 dB SL, .88 at 30 dB SL, and .95 at 40 dB SL. It was concluded that the word lists have strong test-retest reliability at 20, 30, and 40 dB SL and that the reliability increases as the presentation level increases.

The purpose of this study was to evaluate an updated list of digitally recorded Speech Recognition Threshold (SRT) materials for test-retest reliability. Chipman (2003) identified 33 psychometrically equated spondaic words that are frequently occurring in English today. These digitally recorded words were used to determine the SRT of 40 participants using the American Speech-Language Hearing Association guidelines. The participants were between the ages of 19 and 83 years and presented with hearing impairment ranging from normal to severe. The individual's pure-tone averages classified 16 participants with normal hearing to slight loss, 12 participants with mild loss, and 12 participants with moderate to severe hearing loss. The speech materials were presented to participants in one randomly selected ear. The SRT was measured for the same ear in both the test and retest conditions. The average SRT for the test condition was 22.7 dB HL and 22.8 dB HL in the retest condition with an improvement of 0.1 dB for retest but no significant difference was identified. Using a modified variance equation to determine test-retest reliability resulted in a 0.98, indicating almost perfect reliability. Therefore the test-retest reliability was determined to be exceptional for the new SRT words.
