자발화에서 나타난 3-4세 아동의 어중종성 발달

다국어 초록 (Multilingual Abstract)

Coda in word-medial position plays an important role in acquisition of our speech. Not only for normal developing children but also for children with phonological disorders have difficult producing coda in word-medial position. Accuracy of coda in word-medial position has a crucial role as a diagnostic indicator since it has a close relationship with a degree of disorder. Coda in word-medial position only appears in a condition of connecting two vowels and this consonant sequence causes diverse phonological processes to happen. Coda in word-medial position differs in production difficulty by the initial sound in sequence.
Accordingly, this study aims to look into the tendency of producing coda in word-medial position in consideration of optional phonological process in spontaneous speeches of children aged 3-4.
Data was collected from 24 3-to-4-year old children,, without speech or language delays. The children were divided into four groups according to their age(with 6 months age gaps)
The results of the study are as follows:1) For coda in word-medial position, sonorant showed high production frequency in manner of articulation, and alveolar in place of articulation. When coda in word-medial position is connected to an initial sound in the same place of articulation, it revealed high frequency of production. 2) Coda in word-medial position revealed a high error rate when it is followed by an initial sound of alveolar stop. Error pattern of regressive assimilation predominantly appeared. Besides, in coda word-medial position, optional process appeared in numbers. 3)The biggest difficulty revealed in producing coda in word-medial position was with velar stop/k ̚/, followed by Bilabial Stops /p ̚/, Bilabial nasal/m/, alveolar nasal/n/, velar nasal/ ŋ/ and Lateral sound/l/ in the order.
Such a result suggests that in targeting coda error in word-medial position for treatment, we should consider optional phonological process as well as a following initial sound.
