Abstract

This study explored the potential impact of pronunciation instruction on L2 listening comprehension. Seventy-two intermediate Vietnamese EFL university learners formed two groups. The pronunciation group (n=35) received seven weekly 45-minute pronunciation instruction sessions targeting segmental and suprasegmental features of English. The control group (n=37) did not receive any pronunciation instruction. Weekly reflections, an exit questionnaire and focus group interviews were used to investigate learners’ perceptions of the impact of the pronunciation instruction. Results showed that the two groups’ immediate listening posttest scores did not differ significantly after the first two sessions on syllables and consonants/vowels. However, the pronunciation group outperformed the control group after three further pronunciation sessions on word stress, thought groups and sentence focus, but these differences disappeared on subsequent immediate and delayed post-tests. Self-report data indicated learners’ positive perceptions of the helpfulness of the pronunciation instruction and how the gained pronunciation knowledge helped improve their listening comprehension.
