Abstract

Vowel articulation in subjects related to speech disorders seems to be difficult. A chant method that properly reflects the characteristics of language could be used as an effective way of addressing the difficulties. The purpose of this study was to find out whether the chant method is effective as a means of enhancing vowel articulation. The subjects of this study were 60 normal adults (30 males and 30 females) in their 20s and 30s whose native language is Korean. Eight utterance conditions including chanting and reading conditions were recorded and their acoustic data were analyzed. The results of the analysis of the acoustic variables related to the formant confirmed that the F1 and F2 values of the vowel formants are increased and the direction of movement of the center of gravity of the vowel triangle is statistically significantly forwarded and lowered in the chant method in both the word and the phrase context. The results also proved that accent is the most influential musical factor in chant. There was no significant difference between four repeated tokens, which increased the reliability of the results. In other words, chanting is an effective way to shift the center of gravity of the vowel triangle, which suggests that it can help to improve speech intelligibility by forming a desirable place for articulation.

모음의 조음은 발화 시 자음과 결합하여 인접한 자음의 조음에 영향을 미칠 수 있기 때문에 정확한 조음위치를 형성하고 적절한 구강개방을 이루는 것이 중요하나 언어병리 분야의 다양한 대상자들은 이에 어려움을 보인다. 따라서 이들을 위한 치료를 위해서 언어의 특성을 적절히 반영하고 있는 노래(챈트)가 효과적인 도구로 사용될 수 있다. 본 연구에서는 챈트조건과 읽기조건에 따른 모음 특성을 비교하여 챈트조건이 모음 발화 강화의 수단으로 적절한지를 알아보고자 하였다. 연구 대상은 한국어를 모국어로 하는 20~30대 일반 성인 60명(남 30명, 여 30명)이었으며, 모음 /이/, /아/, /우/가 포함된 챈트 및 읽기 과제를 각 4회씩 반복 발화하도록 하여 녹음한 뒤 음성 자료를 분석하였다. 음향 변수를 분석한 결과, 읽기조건과 비교해 챈트조건 발화에서 F1, F2 값이 더 커지고, 모음 삼각형 무게중심의 이동 방향이 전방화, 하강화 된다는 의미 있는 결과를 확인하였다. 남녀 비교 시 여성의 값이 유의하게 컸고, 4회 반복 발화 간에 차이를 보이지 않아 결과의 신뢰도를 높였다. 발화조건 중 단어 수준과 구 수준에 따른 차이는 대부분 보이지 않았으며, 챈트조건의 음악요소에는 악센트가 영향을 미치는 것으로 나타났다. 이와 같은 결과는 챈트의 사용이 웅얼거리는 듯한 발화를 하는 대상자들에게 적절한 구강개방을 이루도록 도울 수 있으며, 후방화된 조음 위치로 인해 오조음을 보이는 이들에게 모음의 무게중심을 이동시키는 효과적인 방법이 될 것임을 시사한다.
