Computer-assisted pronunciation teaching (CAPT) software has been developed to improve learners’ pronunciation. CAPT software helps learners to study independently, selecting what function to use and how often they utilize it. CAPT systems are regarded as a useful tool for pronunciation training for learners, specifically those who feel uncomfortable having their pronunciation corrected in front of other learners. This study investigated the effects of computer-assisted pronunciation teaching (CAPT) on Iranian intermediate EFL learners’ pronunciation ability. The researchers used Accent Master Software (AMS) for this objective. A total number of seventy EFL learners were selected based on their performance on Quick Placement Test (QPT). Then, they were randomly divided into two groups (one experimental and one control group). Pre-test of pronunciation was administered to both groups at the beginning of the study to examine their pronunciation before introducing the treatment. Then, CAPT (here AMS) was introduced to the experimental group and the control group received the traditional way of teaching pronunciation. Afterward, both groups attended the post-test. The data were analyzed through running the Independent and Paired Samples T-test methods. Based on the statistical analyses, it was concluded that CAPT had a statistically significant effect on Iranian intermediate EFL learners’ pronunciation. The results also indicated that there was a statistically significant difference in the post-test scores between the control and the experimental groups. That is, the experimental group outperformed the control group in the post-test of pronunciation and the progress within the group for the experimental group was higher than that of the control group.

已经开发了计算机辅助发音教学（CAPT）软件来提高学习者的发音。CAPT软件可以帮助学习者独立学习，选择要使用的功能以及使用频率。CAPT系统被认为是用于学习者的语音培训的有用工具，特别是那些对在其他学习者面前纠正其发音感到不舒服的人。本研究调查了计算机辅助发音教学（CAPT）对伊朗中级英语学习者发音能力的影响。研究人员为此目的使用了Accent Master Software（AMS）。根据他们在快速分班考试（QPT）中的表现，选择了70名EFL学习者。然后，将它们随机分为两组（一组为实验组，另一组为对照组）。在研究开始时，对两组患者都进行了语音预测试，以在引入治疗之前检查他们的发音。然后，CAPT（此处为AMS）被引入实验组，而对照组则接受了传统的发音教学方法。之后，两个小组都参加了后测。通过运行独立样本和配对样本T检验方法分析数据。根据统计分析，得出的结论是，CAPT对伊朗中级英语学习者的发音有统计学意义的影响。结果还表明，对照组和实验组之间的测试后评分存在统计学上的显着差异。那是，
