초록

본 연구는 장애음성의 평가에 사용되는 연속발화과제로서 유성음 문장의 임상적 유용성을 알아보기 위한 것이다. 이를 위해, 모음연장발성과제의 음향학적 측정치인 주파수 변동률(jitter percent, jitter), 진폭 변동률(shimmer percent, shimmer), 소음대배음비(Noise to Harmonic Ratio, NHR)와 유성음으로만 이루어진 연속발화과제의 음향학적 측정치로 캡스트럼 분석 측정치인 켑스트럼 피크 현저성(Cepstral Peak Prominence, CPP), 저주파수대고주파수 스펙트럼비(Low/High spectral ratio, L/H ratio)의 상관을 분석하였다. 음성장애 환자 65명을 대상으로 수집된 자료를 분석한 결과, 유성음 문장의 음향학적 측정치인 CPP와 모음연장발성의 측정치인 jitter(r = -.624, p = .000), shimmer (r = -.530, p = .000), NHR(r = -.469, p = .000) 간에 유의한 상관이 나타났다. 이는 유성음 문장의 캡스트럼 측정치가 '연속발화 과제의 변동률 기반 분석 불가능', '분석구간과 길이에 따른 결과차이' 등 언어재활 임상현장이 가지고 있는 장애음성의 음향학적 분석의 제한에 대한 대안으로 유용하게 사용될 수 있음을 시사한다.

This study aimed to investigate the clinical utility of voiced sentence tasks for voice evaluation. To this end, we analyzed the correlation between perturbation-based acoustic measurements [jitter percent (jitter), shimmer percent (shimmer), Noise to Harmonic Ratio (NHR)] using sustained vowel phonation, and cepstrum-based acoustic measurements [Cepstral Peak Prominence (CPP), Low/High spectral ratio (L/H ratio)] using voiced sentences. As a result of analyzing data collected from 65 patients with voice disorders, there was a significant correlation between the CPP and jitter (r = -.624, p = .000), shimmer (r = -.530, p = .000), NHR (r = -.469, p = .000).This suggests that the cepstrum measurement of voiced sentences can be used as an alternative to the analysis limitations of the pathological voice such as not possible perturbation-based acoustic measurement, and result difference according to the analysis section.
