Pronunciation is critical for English oral language proficiency because of its immediate role in language judgments. However, effective and targeted English pronunciation instruction is scarce. Given the need for pronunciation instruction and the undeniable impact of suprasegmentals on intelligibility and on comprehensibility, the Supra Tutor, a four-module online pronunciation tutor focusing on suprasegmentals, was developed. This mixed methods study assessed the impact of the Supra Tutor on the comprehensibility of international teaching assistants (ITAs). Participants were evaluated for comprehensibility before and after training. The study also examined ITAs’ perceptions of the Supra Tutor in terms of usefulness, engagement, and overall quality. Findings indicated that the Supra Tutor can provide effective pronunciation instruction and engage learners to successfully complete the training. Research and pedagogical implications of the Supra Tutor and its contribution to pronunciation instruction are discussed.
