Second language learners often find it difficult to assess their own pronunciation; however, research shows that self-assessment activities improve learning outcomes and that learners develop more autonomy as they become increasingly proficient at regulating their performance. Unfortunately, studies that look specifically at self-assessment of pronunciation are limited. Therefore, we seek to determine if self-assessment activities can improve L2 English learners’ pronunciation of some consonants that are typically challenging: “th” and “h.” Learners tend to substitute the “th” sounds /θ, ð/ with /t, d/ or /s, z/, and, for some L1s, to delete /h/, and, in some cases, insert /h/. Advanced ESL learners from a variety of L1 backgrounds completed a read-aloud pre-/post-test, which established progress in the pronunciation of these sounds. The test group completed weekly self-assessment activities where they analyzed their own recorded speech. The control group did not complete the self-assessments. Test group participants were also interviewed regarding their impressions of the self-assessment activities and their pronunciation progress. Qualitative data suggests that the self-assessments improved learners’ attitudes and global awareness of their strengths and weaknesses. Quantitative analyses show that both groups improved on /h/ and /θ/, but not on /ð/. Discussion addresses group differences from a developmental viewpoint and offers suggestions to improve self-assessment of L2 pronunciation.
