The Effect Of The Slope Of The Psychometric Function On The Measurement Of Speech Recognition Threshold Using A Male Talker, Nujod Ali Bakhsh
The Effect Of The Slope Of The Psychometric Function On The Measurement Of Speech Recognition Threshold Using A Male Talker, Nujod Ali Bakhsh
Theses and Dissertations
Speech audiometry is the aspect of audiology that provides critical information on how individuals hear one of the most important sounds of daily life: speech. The speech recognition threshold (SRT) is a measure of speech audiometry that is widely used to provide information on an individual's capacity to hear speech. Over time, researchers and clinicians have worked to improve the SRT by developing and modifying a variety of word lists to be used during testing. Eventually, spondaic words were selected as the best stimuli for the SRT. The spondaic words had to meet four criteria: familiarity, phonetic dissimilarity, normal sampling …

The Effect Of The Slope Of The Psychometric Function On The Measurement Of Speech Recognition Threshold Using A Female Talker, Jessica Lee Reese
Theses and Dissertations
Speech audiometry has long been a component of a thorough audiological examination. The speech recognition threshold (SRT) measurement is perhaps the most widely used measurement in speech audiometry. For decades, researchers and clinicians have worked to create and fine-tune word lists that for use in SRT testing; their aim being to improve the accuracy for classifying a client's ability to hear and comprehend speech. Experts in the field have agreed to follow four tenets of speech audiometry when selecting word sets. This study examined whether improvement to stimulus lists for SRT measurement could be made in regards to the tenet …
Development Of Psychometrically Equivalent Speech Recognition Threshold Materials For Native Cebuano Speakers, Melissa Dawn Anderson
Development Of Psychometrically Equivalent Speech Recognition Threshold Materials For Native Cebuano Speakers, Melissa Dawn Anderson
Theses and Dissertations
While there is a clear and immediate need for reliable speech audiometry materials to evaluate the speech recognition threshold (SRT), these recorded materials are not available in Cebuano, a language of the Philippines with 15.8 million speakers. The purpose of this study was to develop, digitally record, evaluate, and psychometrically equate a set of Cebuano trisyllabic words for use in measuring the SRT. To create the SRT materials, common Cebuano trisyllabic words were digitally recorded by a male talker of Cebuano and presented for evaluation to 20 native speakers of Cebuano with normal hearing. Based on psychometric performance, a set …
Psychometrically Equivalent Trisyllabic Words For Testing Spanish Pediatric Speech Recognition Thresholds, Jessica Lee Graham
Psychometrically Equivalent Trisyllabic Words For Testing Spanish Pediatric Speech Recognition Thresholds, Jessica Lee Graham
Theses and Dissertations
The purpose of this study was to use previously recorded Spanish trisyllabic words tested on adults in the measurement of the speech recognition threshold of Spanish-speaking children in order to (a) determine the words' appropriateness when testing children and (b) compare psychometric functions between adults and children. A selection of 28 frequently used trisyllabic words was chosen from previously recorded samples of male and female adult native speakers of Spanish. These words were then presented to 20 native Spanish-speaking children with normal hearing between the ages of 4 and 8 years. The words were presented starting at -5 dB HL …
Test-Retest Reliability Of Speech Recognition Threshold Material In Individuals With A Wide Range Of Hearing Abilities, Karin Leola Caswell
Test-Retest Reliability Of Speech Recognition Threshold Material In Individuals With A Wide Range Of Hearing Abilities, Karin Leola Caswell
Theses and Dissertations
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 …
Test-Retest Reliability In The Determination Of The Speech Recognition Threshold, Alyssa Montierth Jacobs
Test-Retest Reliability In The Determination Of The Speech Recognition Threshold, Alyssa Montierth Jacobs
Theses and Dissertations
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 …
Development Of Psychometrically Equivalent Speech Recognition Threshold Materials For Native Speakers Of Samoan, Jennifer Lane Newman
Development Of Psychometrically Equivalent Speech Recognition Threshold Materials For Native Speakers Of Samoan, Jennifer Lane Newman
Theses and Dissertations
The speech recognition threshold (SRT) is an important measure, as it validates the pure-tone average (PTA), assists in the diagnosis and prognosis of hearing impairments, and aids in the identification of non-organic hearing impairments. Research has shown that in order for SRT testing to yield valid and reliable measures, testing needs to be performed in the patient's native language. There are currently no published materials for SRT testing in the Samoan language. As a result, audiologists are testing patients with English materials or other materials not of the patient's native language. Results produced from this manner of testing are confounded …
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
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 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 …
