摘要
文章从汉语语音评价系统设计的需要出发,针对DTW算法和汉语音节的特点,研究并实现了汉语音节中声母和韵母分割的两种算法,算法依据的基础都是依据不同类语音段数据相异的原理.在实际系统测试中,发现基于段间距离的分割算法取得了良好的实验结果,可以作为汉语语音评价系统中的声韵分割算法.
Considering the demand of Chinese speech assessment system design, and according to the DTW algorithm and the Mandarin characteristics, two of C/V segmentation algorithms in Chinese syllable are studied and implemented. Both of them are based on the discrimination among speech segments belonging to various classes. It is found that the segmentation method based on measurement of the distance between segments achieves good performance. So this algorithm is competent for the C/V segmentation in Chinese speech assessment system.
