Abstract

Objectives: Most studies have examined the developmental error patterns of speech sounds based on elicited word productions. However, this study investigates the phonological characteristics of speech sound productions in conversational speech in 2- and 4-year-old children. The application of articulation tests for the Korean language were administered and the analyses of the phonological error patterns were conducted.
Methods: A total of forty typically developing monolingual Korean children, twenty children per group in the ages of 2 and 4, who had no speech, language, hearing or cognitive problems, and participated. Speech samples were collected at the participants’ homes during daily activities, including play and regular conversations with their mother. A total of 50 eojeols were analyzed. The error patterns for each age group were examined.
Results: Syllable deletion, coda deletion, liquid deletion, stopping, affrication, gliding, fronting, and tensing were found in a quarter of 2-year-old children. Early phonological error patterns (syllable deletion & word-final coda deletion) appeared to disappear by age 4. Word-medical coda deletion, liquid deletion, stopping and tensing are found in a quarter of 4 year-old children. There were quite a few omissions and assimilations of phonemes in younger children, which appeared to be related to conversational speech as opposed to elicited word productions.
Conclusion: The results depicted the early and late developmental phonological error patterns in Korean conversational speech. In addition, the clinical implication was discussed with respect to developmental speech disorders.
