Nowadays there are several challenges for English teachers as well as researchers regarding how to teach foreign language pronunciation more effectively. The current study aimed to explore the effect of computer-assisted pronunciation teaching (CAPT) on Persian monolinguals and Turkmen- Persian and also Baloch- Persian bilinguals’ pronunciation considering production and perception. A sample of 48 female mono and bilingual 7th-grade students participated in this study and made the experimental and comparison groups. All the participants took the Oxford Placement Test and accordingly were in the beginner level of English language proficiency (95.83% of the participants’ scores ranged from 0 to 15). The experimental group experienced a technology-based instruction while the comparison group benefited from traditional listen and repeat method of pronunciation teaching. Two Two-way between-group ANOVAs were used to define the influence of CAPT on pronunciation production and perception of the mono and bilingual participants. The results of the study indicated that CAPT had a significant effect on pronunciation production while pronunciation perception was comparatively more enhanced through the traditional method. Regarding mono and bilingualism, it was also found that bilinguals significantly outperformed monolinguals in pronunciation production in both groups while there was no significant difference between them in pronunciation perception. There were also no interaction effects for pronunciation perception or production scores. The results generally showed that CAPT can be beneficial specifically when it is used along with traditional methods at schools in beginner levels.
