| 摘 要： | 研究了九个嗓音音质参数在五个元音七种情感下的显著性差异,为接下来的情感语音合成做准备.数据库来自同一女性发音人在七种情感下录制的语音样本,从中提取得到九个参数.首先对参数作Shapiro-Wilk检验和Kruskal-Wallis秩和检验,从总体上检验各参数在不同情感间的差异显著性,然后采用中位数检验方法分别对各元音各参数作分析,验证秩和检验结果并研究参数的变化规律.分析结果表明：参数NAQ,MFDR、pulseAmp在情感间具有显著性差异,meanF0、pulseAmp、MFDR具有元音无关的情感变化模式.

| Abstract: | The research studies significant differences of nine voice quality parameters in five vowels of seven emotions,which prepares for the work of speech synthesis.The data was extracted from one single female＇s speech in seven different emotions.We firstly performed Shapiro-Wilk test and Kruskal-Wallis test on parameters,in order to test the significant difference of each parameter among various emotions.And secondly,each parameter embedded in each vowel was analyzed by using median test,aiming at testifying the result Kruskal-Wallis test while studying changing patterns of parameters.The result reveals that three parameters which are NAQ,MFDR,pulseAmp have significant differences of emotions and certain emotional patterns that don＇t relate with vowels exist in parameters meanF0,pulseAmp and MFDR. |
