심도 감각신경성 청각장애아동의 자음지각 및 자음산출 연구

A Study of Consonant Perception and Production by Children with Profound Sensorineural Hearing Loss

본 연구에서는 심도 감각신경성 청각장애아동 20명을 대상으로 자음지각검사와 자음산출검사를 실시하여 (1) 자음지각에서 나타나는 특성, (2) 자음산출에서 나타나는 특성, 그리고 (3) 청력손실, 자음지각 및 자음산출 간의 관계를 알아보았다. 연구결과 조음위치와 조음방법에 따라 자음의 지각정확도에 유의한 차이를 보였으나 모음환경과 음절 내 위치에 따라서는 유의한 차이를 보이지 않았고, 조음위치자질 보다 조음방법자질의 지각정확도가 유의하게 높았다. 자음의 산출정확도에 있어서는 모음환경, 조음위치 및 조음방법에 따라 유의한 차이를 보였으나 음절 내 위치에 따라서는 유의한 차이를 보이지 않았으며, 조음방법자질보다 조음위치자질의 산출정확도가 유의하게 높았다. 그리고 PTA, 자음의 지각정확도 및 자음의 산출정확도 간에는 유의한 상관관계를 보이지 않았다.

The purpose of the present study was to analyze the con sonant perception and production in Korean by children with profound sen sorineural hearing loss, and to investigate the relation ships among the consonant perception, consonant production, and degree of the hearing loss. T wenty hearing - impaired children (HI), whose ages rangedfrom 7 to 13 year s, participated in the experiment . All of the subject s were given two test s : the consonant perception and production test. T he result s of the experiment s were as follows : (1) HI s perception scores of con sonant s were significantly different with respect to the articulation places and articulation manner s , but were not different with respect to the vowel context s and positions of the syllables, (2) HI s perception scores of articulation place features were significantly lower than those of articulation manner features, (3) HI s production scores of consonant s were significantly different with respect to the vowel context s , articulation places , and articulation manner s, but were not different with respect to the position s of the syllables . (4) HI s production scores of articulation place features were significantly higher than those of articulation manner features, (5) Pear son s Correlation Coefficient s showed that the correlation s were not significant between any pair s of PTA, HI s perception scores of con sonant s , and production scores of consonants.
