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 …

Samoan Speech Audiometry: Developing Word Recognition Materials For Native Speakers Of Samoan, Emma Lilian Kruger
Theses and Dissertations
Hearing can be evaluated through the presentation of tones or speech. Speech audiometry determines an individual's speech recognition threshold and word recognition score. Traditionally these materials were developed using familiar, frequently used, monosyllabic words. Currently, there are various types of word recognition materials including those which use word lists, short half-lists, and materials which use sentences level stimuli with competing noise. Word recognition materials were first developed in Standard American English; today, materials are now readily available in many other languages. When possible, word recognition materials are developed digitally to standardize their presentation. Currently, no recorded word recognition materials are …
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 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 …
