한국어 이음절어표의 특징 주파수에 관한 연구

Abstract

Speech audiometry is a useful test for obtaining practical information which could not be gotten from the pure-tone audiometer test. Nowadays, Hahm’s Korean disyllabic word lists are the most commonly used word lists for the speech reception threshold test in Korea. The disyllabic word lists should be composed of spondaic words (equally stressed words). The aim of this study is to evaluate the characteristic frequency of Hahm’s disyllabic word lists. Subjects and Method： Two of the Hahm’s disyllabic word lists were evaluated. The word lists were analyzed using an acoustic analysis program that has the MATLAB function. Results：The percentage of disyllabic words in the Hahm’s disyllabic word lists that had the spondaic words pattern were 33%. The characteristic frequencies of these words were equally stressed above 1,000 Hz. Other disyllabic words showed an unequally stressed pattern. The percentage of words that had the first syllable stressed pattern was 31% and the percentage of second syllable stressed pattern was 36%. Conclusion：Some words, which are commonly used in the Hahm’s disyllabic words lists, had an unequally stressed pattern. A new Korean dissyllabic word list needs to use more balanced words that have the characteristic frequency of each word. (Korean J Otorhinolaryngol-Head Neck Surg 2008;51:1099-103)
