본 연구는 만 4-15세까지의 뇌성마비 아동을 대상으로 초기 섭식능력이 조음기관 구조평가와 말 명료도에 영향을 미치는 변인이 무엇인지 파악하고자 하였다. 총 30명의 경직형 뇌성마비 아동을 대상으로 아동의 섭식 능력에 대해 설문하여, 뇌성마비 아동의 조음기관 구조평가와 말 명료도 검사를 실시하였다. 조음기관 구조평가에 영향을 미치는 요인을 분석한 결과 음식삼키기 가능여부와 병원서 섭식에 대한 치료경험여부, 깨물어 씹기 가능여부, 유동식 섭취가능여부, 섭식에 특별한 방법과 도구 사용여부, 식사 중 문제행동여부, 가누기 시작시기에서 조음평가에 긍정적 영향을 미쳤다. 이상의 연구결과에서 보는 바와 같이 경직형 뇌성마비 아동의 초기 섭식능력이 조음기관 구조평가와 말 명료도에 영향을 미치는 것으로 나타났다.

본 연구는 단어 및 자발화 평가를 통해 학령전 아동의 말소리 산출 특성과 평가 관련 양상을 살펴보고자 하였다. 이를 위해 3-5세 일반아동 72명(연령별 각각 24명)을 대상으로 아동용발음검사(APAC)를 실시하고, 연령과 성별에 따른 자음정확도와 명료도의 차이, 자음정확도와 명료도 간 상관관계, 자음 위치 및 조음 방법에 따른 말소리 오류 패턴을 분석하였다. 연구 결과, 자음정확도와 명료도는 연령에 따라 증가하였으나 성별에 따른 차이는 없었고, 상관관계는 5세 집단에서 통계적으로 유의했으며, 말소리 오류 패턴 또한 두 평가에서 다르게 나타났다. 본 연구 결과는 아동의 말소리 산출이 언어단위에 따라 다르게 나타나기에, 이들의 말소리 능력을 적절히 파악하려면 단어뿐 아니라 자발화 평가가 병행되어야 함을 보여주었다. 이는 단어에 대한 자음정확도만으로 언어장애 등급을 판정하는 현재 기준에 대한 재검토와 추가적인 연구가 필요함을 시사한다.

This study examined the effects of phonetic complexity and articulatory severity on Percentage of Correct Consonant (PCC) and speech intelligibility in adults with dysarthria. Speech samples of thirty-two words from APAC (Assessment of Phonology and Articulation of Children) were collected from 38 dysarthric speakers with one of two different levels of articulatory severities (mild or mild-moderate). A PCC and speech intelligibility score was calculated by the 4 levels of phonetic complexity. Two-way mixed ANOVA analysis revealed: (1) the group with mild severity showed significantly higher PCC and speech intelligibility scores than the mild-moderate articulatory severity group, (2) PCC at the phonetic complexity level 4 was significantly lower than those at the other levels and (3) an interaction effect of articulatory severity and phonetic complexity was observed only on the PCC. Pearson correlation analysis demonstrated the degree of correlation between PCC and speech intelligibility varied depending on the level of articulatory severity and phonetic complexity. The clinical implications of the findings were discussed.

The current study examines PCC (percentage of correct consonant), speech intelligibility, and oral motor function between the group of typically developing children and the group of children with Down's syndrome. To 15 children with Down's syndrome (mean CA: 9;7) and 15 typically developing children on receptive language age, the following tests were administered: K-WPPSI (2001), Picture Vocabulary Test (Kim et al., 1995), Oral and Speech Motor Control Protocol for total oral functional score (Robbins et al., 1987), DDK and Assessment of Phonology and Articulation for Children (APAC, Kim et al., 2007) for PCC and speech intelligibility. Pearson correlation coefficients were computed for the total oral functional score, PCC and DDK of each group. The statistical analysis showed that there is no significant difference in total functional score and DDK when IQ was controlled. There was a significant correlation between total oral functional score and PCC in the Down's syndrome group and a significant correlation between total oral functional score and intelligibility in the Down's syndrome group whether IQ was controlled or not. The findings suggest that both cognitive ability and overall oral motor function need to be considered for the intervention to enhance PCC or speech intelligibility of children with Down's syndrome.

This study was aim to compare the phonological error patterns and PCC(Percentage of Correct Consonants) derived from the single word and spontaneous speech contexts of the speech sound disorders with unknown origin(SSD). The present study suggest that the development phonological error patterns and non-developmental error patterns of the target children, in according to speech context. The subjects were 15 children with SSD up to the age of 5 from 3 years of age. This research use 37 words of APAC(Assessment of Phonology & Articulation for Children) in the single word context and 100 eojeol in the spontaneous speech context. There was no difference of PCC between the single word and the spontaneous speech contexts. Significantly different developmental phonological error patterns between the single word and the spontaneous speech contexts were syllable deletion, word-medial onset deletion, liquid deletion, gliding, affrication, fricative other error, tensing, regressive assimilation. Significantly different non-developmental phonological error patterns were backing, addtion of phoneme, aspirating. The study showed that there was no difference of PCC between elicited single word and spontaneous conversational context. And there were some different phonological error patterns derived from the two contexts of the speech sound disorders. The more important interventions target is the error patterns of the spontaneous speech contexts for the immediate generalization and rising overall intelligibility.
