Korean L2 speakers have many problems learning the pronunciation of English words. One of these problems is vowelepenthesis. Vowel epenthesis is the insertion of vowels into or between words, and Korean learners of English typically dothis between successive consonants, either within clusters, or across syllables, word boundaries or following final codaconsonants. The aim of this study was to investigate whether individual differences in vowel epenthesis are more closelyrelated to the perception and production of segments (vowels and consonants) and prosody or if they are relativelyindependent from these processes. Subjects completed a battery of production and perception tasks. They read sentences,identified vowels and consonants, read target words likely to have epenthetic vowels (e.g., abduction) and demonstrated stressrecognition and epenthetic vowel perception. The results revealed that Korean second-language learners (L2) have problemswith vowel epenthesis in production and perception, but production and perception abilities were not correlated with oneanother. Vowel epenthesis was strongly related to vowel production and perception, suggesting that problems with segmentsmay be combined with L1 phonotactics to produce epenthesis.
