| 摘 要： | 连续的汉语三字词声调,由于受声道响应、音联、协同发音和变调规律等的影响,情况很复杂,故其基音提取远远较孤立字困难.文章简述了简化的自相关算法,分析了削波电平值对三字词基频检测的影响,得出了削波电平的取值范围,提出了对三字词基频检测应采取改变削波电平的观点,进而给出了三字词的基音提取方法.实验表明该方法简便、有效,提取成功率高.文章最后根据实验简述了三字词的变调规律和声调模式.

| Abstract: | The continuous Chinese tone of three syllabic word is very complicated and its pitch detection is more difficult than that of isolated word because of the effects of vocal response,syllable conjunction,coarticulation and tone sandhi. In this paper, by using the simplified autocorrelation method, the influence of clipping value on the pitch detection of three syllabic word is analyzed, the range of clipping value is gained,and the viewpoint of various clipping value for the pitch detction of three syllabic word is presented.Based on aforementioned works, the method of pitch detection of three syllabic word is given. Experiment results show that the method is simple, speedy and accurate.Finally,tone sandhi and tone patterns for three syllabic word are discussed based on the experiment. |
