项目摘要
I have developed two methods that enable speaking exercise in a computer-assisted language learning (CALL) system : a method for evaluating prosody of an English utterance made by a learner, and a method for detecting grammatical mistakes included in the learner's utterance. As for prosody evaluation, I developed an estimation method of word importance factors using a decision tree, and obtained a high correlation to human assessment score, which is comparable to correlation between scores given by human evaluators. As for the grammatical mistake detection, I proposed a method for training an n-gram language model from artificially generated sentences with mistakes, and obtained 89.2% word accuracy.
我开发了两种可以在计算机辅助语言学习(CALL)系统中进行口语练习的方法:一种用于评估学习者的英语话语韵律的方法,以及一种用于检测学习者话语中包含的语法错误的方法。在韵律评估方面,我开发了一种使用决策树的单词重要性因素估计方法,并获得了与人类评估分数的高度相关性,这与人类评估者给出的分数之间的相关性相当。至于语法错误检测,我提出了一种从人工生成的有错误的句子中训练n-gram语言模型的方法,并获得了89.2%的单词准确率。
