项目摘要

Chinese retroflex aspirates are generally difficult for Japanese students learning Chinese pronunciation. In particular, discrimination between utterances of aspirated dental and retroflex affricates is the most difficult for Japanese-speakers to learn. For the students' self-learning, the automatic judgment system has been developed using a computer, so as to check their pronunciations by themselves. We extracted the features of correctly pronounced aspirated dental affricates and aspirated retroflex affricates by observing the spectrum evolution of breathing power during both voice onset time and voiced period of sounds uttered by 40 Chinese native speakers. We developed a 35-channel computerized filter bank to analyze the evolution of the breathing power by using MATLAB and then automatically evaluated the utterances of the 50 Japanese students. The success rates of the system were higher than 91% and 95% for aspirated retroflex and dental affricates, respectively.

对于学习汉语发音的日本学生来说，汉语送气卷舌音通常是困难的。特别是，对说日语的人来说，辨别送气牙音和舌音塞音的发音是最难学的。为了方便学生自学，利用计算机开发了自动判读系统，以便学生自己检查发音。通过观察40名汉语母语者发声时和发声期间呼吸功率的频谱变化，提取出正确发音的送气牙音和送气卷舌音的特征。我们利用MatLab开发了一个35通道的计算机化的滤波器组，用来分析呼吸功率的演变，然后自动评估50名日本学生的发音。该系统对吸入性卷曲和牙合音的成功率分别高于91%和95%。
