Abstract

This study aimed to investigate the acoustic differences that occur in diverse sections of sustained vowel phonation, which is often used in an objective speech analysis of voice disorder patients. The subjects included 17 voice disorder patients (vocal nodules) and 12 normal individuals without any voice disorder. The participants' sustained vowel phonation of /a/ was divided into onset, middle, and offset, and the jitter, shimmer, and NHR in each section were analyzed using the MDVP(Multi-Dimensional Voice Program). The Friedman test and post hoc analysis were used. In the vocal nodules group, the jitter, shimmer and NHR were significantly higher in the off section of sustained vowel phonation than in the middle section, and there were no significant differences between the beginning and middle sections. In contrast, in the group of normal individuals, there were no significant differences between any of the sections. The values of the acoustic parameters according to the section of analysis in the sustained vowel phonation are different and the vocal in the end section is significantly more unstable than that in the middle section. The results of this study will be useful for selecting the sections to be analyzed in sustained vowel phonation and interpreting the results of the analysis.

본 논문은 임상에서 음성장애 환자의 객관적 음성 분석 대상으로 주로 쓰이는 모음연장 발성이 분석하는 구간에 따라 어떠한 음향학적 차이를 보이는지 밝히고자 하였다. 본 연구에서는 성대결절 환자 17명의 /아/ 모음연장 발성을 시작, 중간, 끝 구간으로 편집하여 MDVP를 통해 각 구간의 jitter, shimmer, NHR을 산출하였고, 비교를 위하여 정상 음성 집단 12명의 음성도 분석하였다. 산출 결과는 R 통계프로그램을 활용하여 Fridman test와 사후 검정을 실시하였다. 음성장애 환자집단은 모음연장 발성의 끝 구간이 중간 구간에 비해 jitter, shimmer, NHR 값이 모두 유의하게 높은 것으로 나타났다. 또한, 발성의 시작 구간은 중간 구간에 비해 세 파라미터 모두에서 높게 산출됐지만 유의한 차이는 없었다. 반면, 정상 집단은 발성의 시작, 중간, 끝 모든 구간에서 유의한 차이가 없었다. 모음연장 발성은 구간에 따라 음향학적 파라미터의 분석 결과가 다르고 발성 끝 구간에서 중간 구간보다 유의하게 음성이 불안정해지는 것으로 나타났다. 이러한 결론은 임상 현장에서 모음연장 발성의 분석 구간 선택과 결과 해석에 유용하게 활용될 수 있을 것이다.
