The study employed a quasi-experimental design with a mixed-methods approach. Thirty adult learners participated and received communicative English instruction with the systematic integration of pronunciation into oral activities. Corrective feedback was provided naturally during classroom interaction, with an emphasis on recasts and explicit correction. Data were collected through pronunciation tests administered before and after the intervention, as well as classroom recordings used to identify feedback types and learner response patterns. Quantitative results revealed a statistically significant improvement in segmental pronunciation accuracy at the end of the instructional period. Qualitative analysis showed that, although recasts were the most frequently used type of feedback, explicit correction generated higher levels of learner uptake with repair. In addition, recurrent difficulties were identified in the production of specific English consonant and vowel sounds. The findings suggest that oral corrective feedback is an effective pedagogical strategy for promoting the development of segmental pronunciation among beginner-level learners. In particular, explicit correction appears to be especially beneficial in facilitating the immediate identification and modification of phonological errors in learners with limited linguistic proficiency.enhttp://purl.org/coar/access_right/c_abf2Pronunciationcorrective feedbackenglishforeign languagesegmental phoneticsArticle
