For this purpose, a paper-form questionnaire consisting of 32 target mispronunciations was distributed to Indonesian secondary school teachers of English and also to native English speakers. An analysis of the respondentsa? perceptions has discovered that 14 out of the 32 target mispronunciations are pedagogically significant in pronunciation instruction. A further analysis of the reasons for these major mispronunciations has reconfirmed the prevalence of interference of learnersa? native language in their English pronunciation as a major cause of mispronunciations. It has also revealed Indonesian EFL teachersa? tendency to overestimate the seriousness of their learnersa? pronunciations. Based on these findings, the study makes suggestions for better English pronunciation teaching in Indonesia or other EFL countries. %U http://journal.teflin.org/index.php/teflin/article/view/104
