Development Of Thai Speech Audiometry Materials For Measuring Speech Recognition Thresholds, Lauren Alexandra Hart
Development Of Thai Speech Audiometry Materials For Measuring Speech Recognition Thresholds, Lauren Alexandra Hart
Theses and Dissertations
Speech audiometry materials are essential for thorough audiological testing. One aspect of speech audiometry is evaluating an individual's speech recognition threshold (SRT). Recorded materials for SRT are available in many languages; however there are no widely published recorded SRT materials available in the Thai language. The goal of this study was to develop relatively psychometrically equivalent SRT materials for evaluating the hearing abilities of native speakers of the Thai language. To accomplish this, 90 commonly used bisyllabic Thai words were digitally recorded by a male and a female talker and evaluated by 20 native Thai listeners. Twenty-eight words with relatively …

Development Of Tongan Materials For Determining Speech Recognition Thresholds, Lisa Dawn Bunker
Theses and Dissertations
Speech recognition threshold (SRT) is an important clinical measure that validates the pure-tone average (PTA), assists in diagnosis and prognosis of hearing and hearing impairment, and helps identify non-organic hearing impairment. Few published, recorded, and standardized materials exist in languages other than English, which results in audiologists testing individuals using materials developed in a non-native language. Research shows that this is problematic, as certain criterion for SRT testing are not met. Thus, performance may reflect test-language deficiency rather than hearing impairment. Currently, there are no known published materials for use in measuring the SRT in individuals whose native language is …

The Development Of Word Recognition Materials For Native Speakers Of Tongan, Lara Cahoon Seaver
Theses and Dissertations
The purpose of this study was to develop, digitally record, evaluate, and psychometrically equate a set of Tongan bisyllabic word lists for use in measurement of word recognition testing. Commonly used bisyllabic words were digitally recorded by male and female native talkers of Tongan. The psychometric performance of the words was measured at ten intensity levels (- 5 to 40 dB HL) in 5 dB increments by 20 listeners with normal hearing acuity. The 200 words with the highest rate of listener identification were included in four relatively psychometrically equivalent word lists of 50 words each and eight half-lists of …
The Effect Of Regional Dialect On The Validity And Reliability Of Word Recognition Scores, Jamie Ann Garlick
The Effect Of Regional Dialect On The Validity And Reliability Of Word Recognition Scores, Jamie Ann Garlick
Theses and Dissertations
The purpose of this study was to examine the effect of talker and listener dialect on the validity and reliability of word recognition scores from two sets of Mandarin speech audiometry materials. Four lists of bisyllabic words in Mainland Mandarin and Taiwan Mandarin dialects were administered to 16 participants of each dialect with normal hearing across two test sessions. The performance on materials presented in the native dialect was compared to performance on non-native dialect assessment to determine validity and reliability of test materials. Statistical analysis indicated significant differences between word recognition scores across test sessions, talker and listener dialect, …
The Effect Of Non-Native Dialect On Speech Recognition Threshold For Native Mandarin Speakers, Nathan Edward Richardson
The Effect Of Non-Native Dialect On Speech Recognition Threshold For Native Mandarin Speakers, Nathan Edward Richardson
Theses and Dissertations
Speech recognition thresholds are used for several clinical purposes, so it is important that they be accurate reflections of hearing ability. Variations in the acoustic signal may artificially decrease threshold scores, and such variations can result from being tested in a second dialect. Thirty-two native Mandarin-speaking subjects (sixteen from mainland China and sixteen from Taiwan) participated in speech recognition threshold testing in both dialects to see whether using non-native dialect test materials resulted in a significantly lower score. In addition, tests were scored by two interpreters, one from each dialect, to see whether the scorer's dialect resulted in a significantly …
