Abstract

|
|
|
This study aims to compare the differences between ‘consonant inventory size’ and ‘phonological variability’ in order to examine the phonological development and characteristics of the late-talkers and typically developing expressive language agematched children and to consider the correlations between them. The study participants included fifteen late-talkers and fifteen typically developing expressive language age-matched children(TED group). The results are as follows. First, as regards consonant inventory size, there was a significant difference between late-talkers and TED group. The late-talkers' consonant inventory size was less than TED group. Second, as regards phonological variability, there was a significant difference between late-talkers and TED group. The late-talkers' phonological variability was higher than TED group. Third, in the case of late-talkers, there was no significant correlation between consonant inventory size and phonological variability; however in the case of TED group, there was a significant negative correlation between consonant inventory size and phonological variability. Therefore, phonological ability should be considered in evaluation and intervention of late-talkers.
