ABSTRACT

The purpose of the present study was to investigate whether children who misarticulate / s/ , / c/ or / l/ show differences in articulation accuracy depending on the vowel environment s, whether each age group shows differences in articulation accuracy of / s/ , / c/ and / l/ in accordance with different vowel environment s, and whether each age group demonstrates different error pattern s depending on the vowel environment s . T he subject s were children who demon strated normal development in articulation except for the misarticulations of / s/ , / c/ or / l/ . One hundred and seventy - six children participated in the present study , 2 to 5 year s in age. Forty - two nonsense syllables of CV and VCV were used as stimuli to elicit the children s responses. T he result s of the study are as follows : (1) the levels of accuracy of / s/ , / c/ , and / l/ were significantly different between different vowels in the context of both CV and VCV; (2) the levels of accuracy of / s/ , / c/ , and / l/ were significantly different between age groups in the context of both CV and VCV; and (3) different error pattern s were found in the productions of / s/ , / c/ , and / l/ in terms of both vowel environment s and age groups.
