Psychometrically Equivalent Bisyllabic Words for Speech Reception Threshold Testing in Arabic

Ratcliff, Elisha Rose 12 July 2006 (has links) (PDF)
The use of speech audiometry is essential in audiological testing. One of the most important elements of speech audiometry is speech reception threshold. To provide services for the growing population of non-English speaking people, audiologists need speech audiometry materials in a variety of languages. The purpose of this study was to develop, digitally record, evaluate, and equate Arabic bisyllabic words for use in testing speech reception threshold. Ninety frequently used bisyllabic words were digitally recorded by a male talker of standard Arabic. These words were presented to 20 normally hearing subjects in 2 dB increments at intensity levels ranging from -10 to 22 dB HL. Psychometric functions were then determined for all 90 words using logistic regression. Words with steep psychometric functions were selected for inclusion in the test CD. The intensities of these selected words were adjusted to match the mean subject PTA within 2 dB, and a list of words was developed which was homogenous with respect to slope and audibility. The words are contained on tracks 2 and 3 of the Brigham Young University Arabic Speech Audiometry Materials (Disc 1.0) CD.
