SPLIS Webinar: Online-Based Intelligibility Instruction for Second Language (L2) Learners

When:  May 17, 2022 from 12:00 PM to 01:00 PM (ET)


As speaking skills in English have become increasingly important in different academic and professional venues as a result of globalization, the issues of intelligibility and comprehensibility, which go to the very core of global communication, have come to the fore (Jenkins, 2000). In so doing, L2 pronunciation instruction should be based on those features which render L2 speech more comfortably intelligible. Previous research has revealed that both segmental and suprasegmental features are conducive to non-native speakers’ production of L2 speech (Kang et al., 2018; Saito et al., 2015). However, little research has examined the effects of intelligibility instruction on L2 learners’ pronunciation gains, especially through an online-based approach. Accordingly, this study examined whether online-based instruction of intelligibility features (i.e., high functional load consonants/ vowels, lexical stress, thought grouping, prominence, and intonation) conjointly resulted in gains in L2 learners global (i.e., intelligibility and comprehensibility) as well as specific (i.e., segmentals and suprasegmentals) aspects of pronunciation proficiency. The results suggest that online-based intelligibility instruction can help L2 learners achieve intelligible and comprehensible speech and offer new directions for future pronunciation classes in global contexts.
