Explicit and implicit training methods for improving native English speakers’ comprehension of nonnative speech

Research on communication difficulties between native and nonnative speakers (NNSs) has generally focused on NNSs. However, native speakers’ (NSs) level of familiarity with nonnative accents can also affect communication. This study investigates whether implicit training (exposure to Korean-accented English through sentence transcription) and explicit training (learning about linguistic differences with a focus on Korean-accented English) can improve NSs’ comprehension of Korean-accented English. Participants in both training conditions showed greater improvement than the control group on sentence transcription tasks but not on multiple choice questions that assessed comprehension of a brief lecture. The results replicate past findings showing the effectiveness of implicit training and provide novel evidence of the effectiveness of explicit training. This suggests that explicit training can be effective in improving NSs’ understanding of short utterances when the training ensures participants have learned the material.
