Abstract

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.

Sumario

El objetivo de esta investigación fue desarrollar, registrar digitalmente, evaluar y equiparar materiales para logoaudiometría que pueden usarse para medir el umbral de recepción del lenguaje (SRT) sin ruido, en hablantes nativos de Mandarin de Taiwan. Se registraron palabras trisilábicas familiares, por hombres y mujeres hablantes de Mandarin de Taiwan y fueron subsecuentemente evaluadas por 20 normo yentes natives en 14 niveles de intensidad (-10 a 16 dB HL), con incrementos de 2 dB. Usando regresión logística, se calcularon las funciones psicométricas en todas las palabras. Se seleccionaron 28 palabras con funciones psicométricas comparativamente considerables y se ajustaron digitalmente para aparearlas a la media del promedio con tonos puros del sujeto (5.0 dB HL). El resultado fue una lista de palabras relativamente homogéneas en el umbral de audibilidad y en el gradiente de la función psicométrica. La media del gradiente para las 28 palabras trisilábicas del Mandarin de Taiwan seleccionadas con hombres y mujeres fue de 11.3%/dB y 11.7/dB, respectivamente.
