This study examined research questions regarding differences in intelligibility levels of spoken English as a Foreign Language (EFL) and the use of pronunciation drills between two groups: control and treatment. The goal of this study was to discover if even short-term use of dedicated pronunciation drills (simple tongue twisters and voice exercises) in the EFL classroom was sufficient to significantly improve pronunciation in the target language. This study also examined some of the historical pedagogies and methodologies used in pronunciation teaching. Lastly, this research investigated whether or not there were any correlations between the use of and non-use of dedicated pronunciation drills within the EFL classroom. The results showed statistically significant improvement in intelligibility in both groups.
