Development of Psychometrically Equivalent Speech Recognition Threshold Materials for Native Cebuano Speakers

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 of 21 trisyllabic words with a psychometric function slope >7%/dB that allowed threshold adjustments to the pure tone average were selected and digitally adjusted. The resulting mean psychometric function slopes at 50% for the 21 SRT trisyllabic materials was 10.2%/dB. The results of the current study are comparable to those found in other languages. Digital recordings of the trisyllabic words are available on compact disc.
