The aim of this research was to develop, digitally record, evaluate, and equate speech audiometry materials that can be used to measure the speech reception threshold (SRT) in quiet for native speakers of Taiwan Mandarin. Familiar trisyllabic words were digitally recorded by male and female talkers of Taiwan Mandarin and subsequently evaluated by 20 native listeners with normal hearing at 14 intensity levels (-10 to 16 dB HL) in 2 dB increments. Using logistic regression, psychometric functions were calculated for all words. Twenty-eight words with comparatively steep psychometric functions were selected and digitally adjusted to match the mean subject pure-tone average (5.0 dB HL). This resulted in a list of words that are relatively homogeneous in threshold audibility and psychometric function slope. The mean slopes for the 28 selected male and female trisyllabic Taiwan Mandarin words were 11.3%/dB and 11.7%/dB, respectively.
本研究的目的是开发、数字录制、评估和等效用于测量台湾普通话母语者在安静环境中言语接受阈（SRT）的言语测听材料。熟悉的三音节词由台湾普通话的男性和女性说话者进行数字录制，随后由20名听力正常的母语听众在14个强度水平（-10至16 dB HL）下以2 dB的增量进行评估。使用逻辑回归，计算所有单词的心理测量函数。选择了28个具有相对陡峭心理测量函数的单词，并进行数字调整以匹配受试者的平均纯音平均值（5.0 dB HL）。这产生了一份在阈值可听性和心理测量函数斜率方面相对均匀的单词列表。所选的28个台湾普通话男性和女性三音节词的平均斜率分别为11.3%/dB和11.7%/dB。
