이 연구는 말장애의 진단에 유용한 일음절 낱말대조 명료도 검사 (낱말명료도)의 타당도와 신뢰도를 얻기 위한 것이다. 첫번째로 낱말명료도의 타당성을 확인하기 위하여 문장명료도와의 상관을 구한 결과 상관은 .83으로 비교적 높았다. 두 번째로는 평가자들 간의 일치도를 분석하였다. 낱말명료도는 명료도 손상의 수준에 상관없이 평가자들간에 일정한 변산을 보였다. 마지막으로 낱말명료도 평가도구를 이용하여 마비말장애인의 명료도를 떨어뜨리는데 주요한 역할을 하는 음소대조 요인을 살펴본 결과 종성이 가장 오류가 많았으며 다음으로 초성, 중성의 순서였으나, 회귀분석 결과 초성이 전체 명료도에 미치는 영향이 가장 컸다.

The relations between words intelligibility and sentences intelligibility were tested on adults with cerebral palsy(athetoid type). Intelligibility is used as an important evaluation value in the field of diagnosis and therapy of dysarthric patients. In order to develop one syllable phonetic contrast intelligibility test using specific phonetic contrasts, the correlation with sentences intelligibility was tested to find out the validity. Pearson's simple correlation coefficient was .83 that shows a high correlation. Also, comparing the range and standard deviation given by seven evaluators on each subject, it was shown that when evaluating patients of moderate intelligibility, words intelligibility was more reliable than sentences intelligibility.

This study examined the speech intelligibility of one-syllable words with phonetic contrasts and analyzed segmental factors that can predict the overall speech intelligibility in hearing-impaired adults. To identify the speech error characteristics, a Korean word list was audio-recorded by 7 hearing-impaired adults, and 35 listeners selected the heard word out of 5 choices. Based in part on previous studies of speech of the hearing impaired, the word list consisted of monosyllabic consonant-vowel-consonant (CVC) real word pairs. Stimulus words included 77 phonetic contrast pairs. The results showed that the percentage of errors in final position (coda) contrast was higher than in any other position in syllable. And the intelligibility deficit factors of phonetic contrast in the hearing-impaired were analyzed through stepwise regression analysis. The overall intelligibility was predicted by the error rate of manner contrast at coda, voicing contrast (homorganic triplets) at onset and high-low contrast at nucleus.

The purpose of this study was to show the characteristics of phonetic contrasts of one-syllable words and speech intelligibility in hearing-impaired adults. Seven subjects with hearing-impaired participated in this experiment(2 males, 5 females). The test materials are 77 pairs of one-syllable words with phonetic contrasts. The results of this study were as follows: (1) The average score of intelligibility(scored accuracy) was the highest in contrasts of onset feature. (2) The scored percentages of error(except for combinations of contrasts) were the highest in articulatory manner contrasts of onset, tongue height contrasts of nucleus, and articulatory place contrasts of coda, respectively.
