본 연구는 4-6세의 정상 아동 25명과 기능적 조음장애 아동 25명을 대상으로 조음장애의 진단을 빠른 시간에 정확히 할 수 있는 검사방법을 찾는 것을 목적으로 하였다. 조음장애의 진단을 위해 자음정확도와 명료도를 평가지표로 삼고 낱말검사, 문장검사 및 대화검사의 세 가지 검사방법에 따른 차이를 분석하였다. 연구결과 43개의 목표자음에 대한 자음정확도는 두 집단(정상 집단, 조음장애 집단) 모두 조음검사 방법에 따라 통계적으로 유의미한 차이가 없었다. 또한 두 집단 모두 자음정확도와 명료도에서 강한 정적 상관관계를 보였다.

When testing a child with articulatory- phonological disorders, it might be ideal to test both the correctness of consonant s and the intelligibility of his/ her spontaneous, connected speech. However , there are occasions which make it impossible to test the connected speech due to either or both of the following factor s : the lengthy time required to administer a test and the unintelligibility of a subject s speech. One way which could overcome this difficulty might be to predict the level of intelligibility based on the percentage of consonant s correct of the child in concern. The purpose of the present research is to investigate this possibility. Fifty subject s participated in the ex periment : an experiment al group of 25 childr en with function al articulat ory - phonological disorders and a control group of 25 normal children. Three tests were administered to the subjects : (1) the word test , which was to get the percentage correct of the 19 Korean consonants in 23 words, (2) the sentence test, in which the same set of 23 words were embedded in sentences, the purpose of which was to get the percentage correct of the 19 Korean consonant s in the sentential environments, and (3) the test of connected speech, which provided the data on the percentage correct of the consonants and the scores on intelligibility of the words. In the case of the connected speech, 70 utterances per child were collected on the separate criteria to calculate the percentage of consonant s correct and the intelligibility scores. The results were shown as follows: (1) As for the percentage of consonant s correct , MANOVA with repeated measures was carried out and it was found that there was a group difference between the children with articulatory- phonological disorder s and the normal children. However, no statistically significant difference was found between different methods of testing, i.e., between the word test , the sentence test , and the test of connected speech, in both groups of children with arcticulatory- phonological disorders and normal children, respectively ; (2) Pearson s Simple Product -Moment Correlation Coefficients were obtained for each group of subjects, and it was found that there was a statistically significant correlation between the percentages of consonants correct and the scores of intelligibility in either group, in respect to the three tests. Therefore, we might conclude, with some caution, that we could feasibly predict the level of intelligibility on the basis of the score of consonant s correct, either that of the word test or that of the sentence test.
