Abstract
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.
