This study examined the effect of information and communication technology supported media on pronunciation of some English words in selected secondary schools in Ilorin Metropolis. The study targeted all senior secondary school II students in Ilorin Metropolis. Sixty second year senior secondary school students were sampled from three public secondary schools in Ilorin, Kwara State, Nigeria. Pre-test post-test experimental control group design was employed. English Language Pronunciation Achievement Test (ELPAT) was used to collect necessary data. The pre-test and post-test data were analyzed using One-way ANOVA and t-test statistics. Findings of study showed that performance of students exposed to Electronic Encarta Dictionary audio version pronunciation and those exposed to CDROM audio version pronunciation were better than their counterparts exposed to the conventional classroom instruction. However, there was no significant difference in the performance of male and female students exposed to Electronic Encarta Dictionary audio version pronunciation and CDROM audio version pronunciation. Based on the findings, it was recommended that English language teachers should always adopt ICT supported media for their teaching and learning activities in and outside the school.
