배경 및 목적: 조음장애에 대한 임상적 의사결정에는 자음정확도 외에 의사소통의 효율성에 대한 지표도 포함시키는 것이 중요하다. 본 연구는 구개열 아동의 문장발화에 대해 산출된 자음정확도, 말 명료도 및 말 용인도가 어떠한 관계를 갖는지 알아보는 데 그 목적이 있다. 방법: 연령을 일치시킨 구개열 아동, 기능적 조음장애 아동, 일반 아동 각각 9명에게 8음절 문장 7개를 따라 말하게 하여 63개 문장 발화의 자음정확도를 산출하였다. 그 다음, 문장 발화 를 무선화하여 청취자료로 제작한 뒤 일반인 청취자 40명에게 들려주고 시각적 아날로그 척도 를 사용하여 말 명료도와 말 용인도를 평정하게 하였다. 이후 전체 문장, 문장 유형별, 자음정 확도, 말 명료도 및 말 용인도 수준별로 산출된 자음정확도, 말 명료도 및 말 용인도 간의 상관분석을 실시하였다. 결과: 전체 문장에서 판정된 자음정확도와 말 명료도, 자음정확도와 말 용인도, 그리고 말 명료도와 말 용인도 간의 상관은 세 아동 집단에서 모두 유의하였다. 문장의 유형을 구분하여 자음정확도와 말 명료도, 자음정확도와 말 용인도의 관련성을 분석한 결과, 각 집단별로 유의한 상관을 보인 문장 유형은 다르나 대체로 혓소리와 발달상 늦게 습득되는 자음 문장에서 상관이 유의하였다. 자음정확도, 말 명료도 및 말 용인도의 수준에 따라 세 변인 간의 관련성을 분석한 결과, 대체로 말 명료도와 말 용인도 간의 상관 외에는 유의하지 않았다. 논의 및 결론: 문장발화에서 판정된 자음정확도가 높을수록 말 명료도와 말 용인도도 높게 평가될 수 있다. 자음정확도 외에 말 명료도와 말 용인도의 판정에 미칠 수 있는 여러 조음 변인을 논의하였다. 말 명료도와 말 용인도 간의 상관도가 매우 높게 나타 났으나, 두 변인에 작용하는 조음 변인이 다를 수 있음을 논의하였다.

Background & Objectives: It is important to account for the index of communication effectiveness as well as the percentage of correct consonants (PCC) in clinical decision-making when treating patients with articulation-phonological disorders. The purpose of the current study was to examine whether there is a correlation among the PCC, speech intelligibility, and speech acceptability of children with cleft palate (CP). Methods: Nine children with cleft palate, nine children with functional articulation disorder, and nine children without developmental abnormalities, all three to six years of age and age-matched, participated in this study. All subjects were asked to repeat seven eight-syllable sentences. Each utterance was judged in regard to correct articulation of the target sounds, and a PCC score was calculated for each sentence. After listening to each sentence, 40 naive listeners were asked to rate both the speech intelligibility and speech acceptability of each sentence on a 10㎝ Visual Analog Scale. Results: The PCC scores, speech intelligibilities, and speech acceptabilities of the sentences produced by children with cleft palate were significantly related. A significant relationship among the PCC score, speech intelligibility, and speech acceptability ratings for lingual consonants and consonants that are generally acquired later during development was detected. The correlations between the PCC scores and the speech intelligibility ratings, and the PCC scores and the speech acceptability ratings were not significant when analyzed by level of PCC, speech intelligibility, and speech acceptability. Discussion & Conclusion: Although speech intelligibility and speech acceptability are influenced by PCC score, they are not interchangeable measures. Variables that may underlie the relationships between PCC, speech intelligibility, and speech acceptability was discussed.
