The purpose of this study was twofold: (1) to identify the most frequent techniques of teaching pronunciation used by Iranian EFL teachers and, (b) to find out any relationship between teacher's extroversion/introversion personality type and their techniques of teaching pronunciation. To this end, following an online survey a cohort of 60 teachers out of 200 participated in this study. Based on the results of Eysenck Personality Inventory (EPI) questionnaire, they were classified into introvert and extrovert groups. Then, a checklist was used to elicit their mostly favored techniques of teaching pronunciation. The collected data were analyzed through SPSS software. The results of descriptive analysis indicated that from among 19 pronunciation teaching techniques, listen and imitate and reading aloud and recitation were the most frequent ones used by both introverted and extroverted teachers. Moreover, the results of chi-square test showed a significant relationship between the extroverted and introverted teachers in the use of pronunciation techniques and that the extroverted teachers significantly used more of the mentioned techniques than the introvert teachers.
