This study is aimed at finding out the effect and efficiency of oral repeated reading (RR) on oral reading fluency in the EFL environment in Taiwan. By prompting oral reading speed and automaticity, RR proved an effective method to enhance both oral reading and speaking fluency. The results indicated that there was a significant improvement in oral reading speed before and after the intervention, regardless of the following factors: (a) gender, (b) native language, (c) time using/learning English during off-training time, and (d) pre-test performance, and (e) improvement gained during the practice. Replies from post-test questionnaires also indicated a high acceptability of RR among subject groups. Accordingly, the adoption of RR for automaticity development and speed training in oral fluency instruction was recommended for future teaching in Taiwan.
