While recorded speech audiometry materials have been developed in Spanish for adults, currently there are no speech audiometry materials available in Spanish that are suitable for a pediatric population. Thus, the purposes of this study were (a) to analyze Spanish bisyllabic words previously developed for adults to determine the words' appropriateness when testing word recognition scores in native Spanish-speaking children and (b) to compare the logistic regressions results from the Spanish adult data obtained in a previous study with the logistic regressions from Spanish pediatric data obtained in the present study. Using common-use children's dictionaries in the Spanish language, a subset of child-appropriate words was adapted from a set of materials developed for Spanish adults. A total of 129 frequently used bisyllabic words were chosen; the words were split into five lists; four lists contained 26 words and one list contained 25 words; each was digitally recorded by both male and female Spanish talkers. Twenty native Spanish-speaking children with normal hearing between the ages of four and eight years were selected to listen to words to obtain psychometric functions. Each word was presented to the listener at 5 levels of intensity from -5 to 35 dB HL in increments of 10 dB. Custom software was used to control randomization, timing, and presentation of the words. The participants were not familiarized with the words prior to testing. The words received a ranked order based on performance to create lists and half-lists that were equivalent. Logistic regression was used to calculate psychometric functions for the lists and half-lists. Subsequently, a chi-square analysis was completed. The analysis revealed no statistical differences among the lists and half-lists for either male or female talkers. The mean bisyllabic psychometric function slopes for lists and half-lists were 5.0%/dB for the male-talker words and 5.2%/dB for the female-talker words. The 50% threshold for male and female were 16.2 dB HL and 15.5 dB HL, respectively.

The purpose of this study was to record a set of Mongolian monosyllabic word lists that could be used to obtain a word recognition score. A word list was developed of 190 frequently used monosyllabic words which had been selected by a group of raters. Native male and female Mongolian talkers were utilized to make digital recordings. The 190 words were divided into 10 lists of 19 words. The lists were presented to 20 normally hearing subjects at 10 different intensity levels ranging from -5 to 40 dB HL in 5 dB increments. An S-curve distribution was used to divide the words among three lists based upon the results of the word recognition testing. Word lists were assembled formulating 3 lists of 50 words and 6 half-lists of 25 words using an S-curve distribution. Logistic regression was used to calculate the psychometric functions for each list. The mean psychometric function slopes for the male and female word lists were 6.19%/dB and 5.17%/dB respectively. The 50% threshold was 14.47 dB HL for the final adjusted male and female lists.

The aim of this study was to develop, digitally record, evaluate, and psychometrically equate a set of Taiwan Mandarin bisyllabic word lists to be used for word recognition testing. Frequently used bisyllabic words were selected and digitally recorded by male and female talkers of Taiwan Mandarin. Twenty normally hearing subjects were presented each word to find the percentage of words which they could correctly recognize. Each word was measured at 10 intensity levels (-5 to 40 dB HL) in increments of 5 dB. Logistic regression was used to include 200 words with the steepest logistic regression slopes in four psychometrically equivalent word lists of 50 words each with eight half-lists of 25 words each. Digital recordings of the psychometrically equivalent bisyllabic word recognition lists are available on compact disc.

The purpose of this study was to create psychometrically equivalent word lists in the language of Cantonese for word recognition testing. Frequently used bisyllabic Cantonese words were recorded by a native female and male talker. The word lists were evaluated by administering the word recognition lists to 20 native speakers of Cantonese with normal hearing. Each list was presented at 10 different intensity levels ranging from -5 to 40 dB HL in 5 dB increments. Logistic regression was used to determine the words with the steepest logistic regression slopes. The 200 words with the steepest slopes were then formulated into four lists of 50 words and eight half-lists of 25 words. The mean psychometric slope value at the 50% location for the male talker was 7.5%/dB while the mean slope for the female talker was slightly steeper at 7.6%/dB. The word lists were digitally recorded on compact discs for worldwide use.
