提出了一种适用于母语非汉语学习者（Learner with Mandarin as a second language，ML2）学习汉语的自动发音评分（Automatic Pronunciation Evaluation，APE）方法。引入双语料语音库，将发音评分分为发音方式和发音效果两部分评分，提取各部分相应的特征参数，提出一种双语音动态时间规整（Bilingual Dynamic Time Warping， BDTW）的方法来匹配比较得到语音相似度，通过评分机制得到最后的评分结果。通过实验验证了该方法的有效性。

A method for automatic pronunciation evaluation is proposed, applying to the learners with Mandarin as a sec-ond language learning Chinese. Bilingual language speech database is introduced and the evaluation is divided into two parts, which are the manner of articulation and pronunciation. This paper extracts the parameters of each part and makes use of the improved method based on comparison of speech similarity, an algorithm named Bilingual Dynamic Time Warping. It gets the final result by means of score mechanism. Experiments verificate the validity of the system.
