The purpose of this study was to develop, digitally record, evaluate, and equate Mongolian monosyllabic and bisyllabic child-appropriate words which can be used in the measurement of word recognition scores and speech-reception threshold (SRT) in children who are native speakers of Mongolian. Based on data collected from a survey of Mongolian child language professionals, a subset of child-appropriate materials was adapted from a set of materials developed for Mongolian adults. Two lists of 50 monosyllabic words and four half-lists of 25 words each were developed for testing the word recognition abilities of Mongolian children. The developed lists and half-lists were found to be statistically equivalent in terms of audibility and psychometric slope, with average psychometric function slopes (at 50% intelligibility) of 6.41 %/dB for the male recordings and 5.84 %/dB for the female recordings. Given the structure and limitations of the study, a valid set of child-appropriate SRT materials could not be developed. It is likely that the inability to obtain a subset of SRT words was due in part to large differences between the mean PTA of the subjects and the threshold for 50% intelligibility, as well as the inability to represent most of the selected words pictographically. However the information gained from this study provides additional insight that may aid the future development of child-appropriate Mongolian SRT materials. Digital recordings of the resulting psychometrically equivalent child- appropriate speech audiometry materials are available on compact disc.
