This research aims to investigate correlations among syllable accuracy, number of incorrect consonants,
and speech intelligibility of children with articulation and phonological disorders through connected speech
test. To accomplish this, 50 speech samples collected from 7 children were heard to 17 rators of speech
intelligibility, and let them mark with a scale from 1-10 points. A result demonstrated that all the
children got 5 points or below in a speech intelligibility, which is applicable to normal. Correlation
between speech intelligibility and syllable accuracy was .914 in a significant level of 0.01. Further,
correlation between speech intelligibility and incorrect consonants was -.949 in a significant level of 0.01,
indicating that the more incorrect consonants were, the lower speech intelligibility was.
