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
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 …
Development Of Psychometrically Equivalent Speech Audiometry Materials For Measuring Speech Recognition Thresholds In Native Tagalog Speakers, Brandon Brian Taylor
Development Of Psychometrically Equivalent Speech Audiometry Materials For Measuring Speech Recognition Thresholds In Native Tagalog Speakers, Brandon Brian Taylor
Theses and Dissertations
In addition to the use of pure-tones for testing hearing, speech signals are highly valuable diagnostic tools for identifying and evaluating hearing impairment. Speech audiometry involves the implementation of such signals in the measurement of hearing acuity. One aspect of speech audiometry involves assessment of the speech recognition threshold (SRT) which evaluates an individual's ability to hear and understand speech. While live speech has been used in the past to assess SRT, recorded materials are preferred and have been shown to be advantageous over live speech. High-quality digitally recorded speech audiometry materials have been available in English for some time, …
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 Psychometrically Equivalent Speech Audiometry Materials For Testing Children In Mongolian, Meghan Elizabeth Caldwell
Development Of Psychometrically Equivalent Speech Audiometry Materials For Testing Children In Mongolian, Meghan Elizabeth Caldwell
Theses and Dissertations
The purpose of this study was to develop, digitally record, evaluate, and equate Mongolian monosyllabic and bisyllabic child-appropriate words which can be used in the measurement of word recognition scores and speech-reception threshold (SRT) in children who are native speakers of Mongolian. Based on data collected from a survey of Mongolian child language professionals, a subset of child-appropriate materials was adapted from a set of materials developed for Mongolian adults. Two lists of 50 monosyllabic words and four half-lists of 25 words each were developed for testing the word recognition abilities of Mongolian children. The developed lists and half-lists were …
Psychometrically Equivalent Bisyllabic Words For Speech Reception Threshold Testing In Mongolian, Kristen Nicole Gilbert
Psychometrically Equivalent Bisyllabic Words For Speech Reception Threshold Testing In Mongolian, Kristen Nicole Gilbert
Theses and Dissertations
Speech audiometry is an important aspect of audiological testing. One aspect of speech audiometry is the measurement of an individual's speech reception threshold (SRT). Materials needed to measure the SRT are available in many languages; however, recorded materials for the Mongolian Language are not widely available. The purpose of this study was to develop a list of psychometrically equivalent words for evaluating the hearing abilities of native Mongolian speaking individuals. A set of 90 commonly used bisyllabic Mongolian words were digitally recorded by a male and female talker of Mongolian and then evaluated by 20 native Mongolian listeners. A final …

Psychometrically Equivalent Trisyllabic Words For Speech Reception Threshold Testing In Spanish, Laurel Anne Keller
Theses and Dissertations
The purpose of this study was to develop, digitally record, evaluate, and equate Spanish trisyllabic words which could then be used in the measurement of the speech reception threshold. A selection of 90 frequently utilized trisyllabic words were selected and then digitally recorded by male and female talkers of Spanish and presented to 20 subjects with normal hearing beginning at 6 dB below their pure-tone average (PTA) and ascending in 2 dB increments until one of the following criteria had been met: (a) the participant responded correctly to 100% of the test items, or (b) the presentation level reached 16 …

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 …
