This study examined the impact of sonority profiles, positional differences and L2 proficiency on Korean EFL learners' perception of English biconsonantal clusters, using nonce words. The overall results showed that major predictions of the sonority-based typological markedness on consonant clusters were supported, as obstruent plus sonorant and sonorant plus obstruent sequences were better perceived than obstruent only or sonorant only sequences. Yet, some consonant clusters did not show a preference for sonority profiles. Positional effects were also confirmed, as word-initial biconsonantal clusters were better perceived than wordfinal ones across all the participant groups. Participants' English proficiency turned out to be also important in the perception of consonant clusters, since university students' mean rate of accuracy was highest, followed by that of high school students, which in turn followed by that of middle school students. Further, the effects of other factors like frequency and stimuli on speech perception were also addressed, along with some implications for future research.

Motivated by the fact that cluster reduction strategies such as inserting a vowel or deleting a consonant in resolving English complex clusters differ depending on studies, this paper investigates the repair strategies employed by Korean EFL students. A total of 60 college students participated in the present study and the participants' production of English voiceless word-initial and word-final clusters was measured using the materials designed for this study. It has been shown that prosodic positions such as onset and coda and the number of cluster sequences influenced cluster reduction strategies. The error rates of both insertion and deletion were noticeably higher in the coda position than in the onset position and both insertion and deletion error rates were higher in triconsonatal cluster than in biconsonantal cluster sequences. Overall, the insertion rate was higher than the deletion rate. However, the deletion rate was significantly higher than the insertion rate in triconsonantal coda cluster sequences. Because of this, the deletion rate was higher than the insertion rate for triconsonantal cluster sequences across onset and coda. Also, the high deletion rate of triconsonantal coda clusters contributed to the high deletion rate for the coda clusters in general.
