关于汉语普通话元音声学特点的研究

Acoustical Study on Vowels in Standard Chinese

文章主要研究了标准普通话中9个元音发音的声学特征,特别是共振峰模式、特点及共振峰频率的目标值,进而分析了不同发音人之间的共振峰差异情况。总体而言,利用每个元音的前四个共振峰进行话者鉴别时,元音/a/和/i/的话者区分率最高,元音/u/的话者区分率最低,其他元音居中。

Iin this paper the acoustical features of nine vowels of standard Chinese were studied. Their formant pattern,characteristics and the target values were investigated in order to analyze the differences on formant frequencies among different speakers. The results show that the discrimination rates of speakers using/a/and /i/are the best,the discrimination rate using/u/is the worst,and the discrimination rates using other six vowels are between.
