摘要
目前许多计算机辅助英语学习系统在发音错误判定过程上缺乏慎重考虑。描述一个基于sphinx-4的英语口语自动评分系统。提出一种以标准语音的平均发音水平作为发音错误判断依据的新方法,根据该方法的判断结果给出相应的反馈意见。实验结果证明,该方法可以有效降低误判率,提升错误检测的正确率。
Many computer-assisted English learning systems lack careful consideration in pronunciation error determination process cmxently. We describe in the paper a sphinx-4-based automatic oral English scoring system. Also we propose a new method for pronunciation errors determination which takes the average pronunciation level of standard voice as the basis, according to the determination results of this method the corresponding feedback will be given. Experimental results prove that this method can effectively reduce the misjudgement rate and enhance the accuracy rate of pronunciation error detection.
