Objectives: Accuracy of phonemes can vary in terms of phonetic and linguistic contexts of test words. This study aims to examine percentage of consonants correct (PCC) and age of acquisition of consonants in Korean-speaking children in one-syllable word contexts.
Methods: This study included 251 Korean-speaking children aged 2;6 through 5;11 who produced 18 one-syllable words. PCC and PCC-Revised were calculated from 18 initial consonants and 7 final consonants. Two-way ANOVAs were performed whether PCC and PCC-Revised were significantly different according to gender and age. Ages of acquisition across all the initials and finals were determined if 50%, 75%, and 90% of children at a specific age produced correctly.
Results: PCC and PCC-Revised showed significant differences across age groups. The mean PCC for the children at age 2;6 was approximately 80%?85%; and by 4;0?4;11, it climbed to approximately 90%. PCC for children aged 5;0 to 5;11 exhibited approximately 98%. Seventy-five percent or more of the children correctly produced most plosives, nasals, /h/, /t?/, and final /l/ earlier than age 2;6. Final /k/ reached the criterion by 3;5 and /t?*/, /t?h/ reached the criterion by 4;5. Initial /l/, /s/ and /s*/ reached the criterion by 5;5.
Conclusion: This study presented PCC and ages of acquisition of consonants in Korean-speaking children in one-syllable word contexts. This study suggested that children’s sound productions should be assessed and interpreted considering phonetic contexts and linguistic units of test materials.
