Abstract

Speech reception threshold (SRT) tools have been developed to assist in the evaluation of hearing. This study was performed to develop, digitally record, evaluate, and equate Taiwan Mandarin trisyllabic words which can be used to measure the SRT. Eighty-nine commonly used trisyllabic words were chosen and digitally recorded by native male and female speakers. The words were then presented to 20 normally hearing subjects at 14 intensity levels (-10 to 16 dB HL) with 2 dB increments. Psychometric function slopes were calculated using logistic regression. Twenty-eight words with steep psychometric function were selected and digitally adjusted to match the mean subject pure-tone average (5.0 dB HL). A list of 28 trisyllabic words which were relatively homogeneous in audibility and slope were developed. The mean slopes for the 28 selected male and female trisyllabic Taiwan Madarin words were 11.3 %/dB (male talker) and 11.7 %/dB (female talker), respectively. Digital recordings of the psychometrically equivalent trisyllabic words are available on compact disc.
