This report attempts to explain why L2 learners struggle to perceive and produce segments accurately in their L2 and what can be done to help L2 learners overcome these problems. Accordingly, the report explores how L1 experience and segmental differences between Vietnamese and English contribute to these English language learners’ perception and production problems. The report also considers instructional methods that can be used to help ESL learners overcome their perception and production challenges and recommends several approaches for addressing segments that are often difficult for Vietnamese learners.application/pdfengperceptionsegmentsVietnamesepronunciationESLthesis
