Objective:
To analyze speech and linguistic features in children with articulation disorder characterized by consonant and vowel phonological errors.
Methods:
Between February 2007 and June 2015, 117 children who showed articulation disorder were selected for the study. Based on comprehensive speech and language assessments, the subjects were classified into articulation dysfunction (AD), or AD overlapping with language delay. Detailed information of articulation, including percentage of consonants correct (PCC) and normal percentage of variable consonants derived from the Assessment of Phonology and Articulation for Children test, were compared between the two groups.
Results:
Totally, 55 children were diagnosed as AD and 62 as AD with language delay. Mean PCC was not significantly different between the two groups. In both groups, the acquisition order of consonants followed the universal developmental sequence. However, differences were observed in the nasal & plosive consonants abnormality between the two groups. When adjusted to their delayed language level in AD with language delay group, 53% of children had appropriate articulation function for their expressive language level.
Conclusion:
Speech and linguistic characteristics in children with articulation disorder were variable. Therefore, comprehensive assessment is required in children with inaccurate pronunciation, and a proper treatment plan based on the results of assessment should be followed.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
