Background & Objectives: The Korean coda consonant system (syllable-final consonant) differs from the onset system (syllable-initial consonant). The present study investigates coda error patterns in word-medial and word-final positions of Korean children with specific phonological disorders (PD).
Methods: Data were collected from 19 children, 5 to 6 years of age with PD, but no language delay. Twenty-nine words from the Assessment of Phonology & Articulation for Children (APAC) were used to analyze error patterns in 16 word-medial position codas, and 14 word-final position codas.
Results: The findings were as follows: First, a syllable-final consonant in the word-medial position showed more errors than in the word-final position. Second, among types of error (deletion, harmony, substitution etc.), deletion was the most common. Third, the correlation between PCC and the number of each coda error was fairly high.
Discussion & Conclusion: The present study shows the importance of understanding the error patterns observed in word-medial position codas, where deletion is the most common type of phonological process. Continuing to develop the phonological tests for codas in the word-medial position is necessary in order to further support children with PD.
