Studies of learner-learner interactions have reported varying degrees of pronunciation-focused discourse, ranging from 1% (Bowles, Toth, & Adams, 2014) to 40% (Bueno-Alastuey, 2013). Including first language (L1) background, modality, and task as variables, this study investigates the role of pronunciation in learner-learner interactions. Thirty English learners in same-L1 or different-L1 dyads were assigned to one of two modes (face-to-face or audio-only synchronous computer-mediated communication) and completed three tasks (picture differences, consensus, conversation). Interactions were coded for language-related episodes (LREs), with 14% focused on pronunciation. Segmental features comprised the majority of pronunciation LREs (90%). Pronunciation LREs were proportionally similar for same-L1 and different-L1 dyads, and communication modality yielded no difference in frequency of pronunciation focus. The consensus task, which included substantial linguistic input, yielded greater pronunciation focus, although the results did not achieve statistical significance. These results help clarify the role of pronunciation in learner-learner interactions and highlight the influence of task features.
