【摘要】：该文考察了普通话6个塞擦音的声学参数与其语音特征之间的关系。通过Praat软件提取时长、振幅、频谱能量分布、后接元音第二共振峰(F2)起始频率等9个声学参数。通过方差分析,揭示了统计上分别区分3个发音部位、2个送气状态以及2个后接元音的声学参数;判别分析结果显示,9个声学参数的组合对6个塞擦音的辨别率为85.9%;主成分分析结果显示,前5个主成分可以表征塞擦音86.3%的信息。综合3种统计分析结果表明:摩擦段的频谱能量分布是普通话塞擦音最重要的一组声学参数,有些主要表征了发音部位,有些主要表征了送气状态;摩擦段的时长和振幅主要表征了送气状态及后接元音;后接元音的F2起始频率也会受到塞擦音发音部位的影响。
[Abstract]:In this paper, the relationship between acoustic parameters and phonetic features of Putonghua is investigated. Nine acoustic parameters, such as duration, amplitude, spectrum energy distribution and initial frequency of the second resonance peak (F2) of the vowel, were extracted by Praat software. By means of variance analysis, the acoustical parameters of 3 phonetic sites, 2 aspirated states and 2 posterior vowels were statistically distinguished. The discriminant analysis results showed that the discriminant rate of the nine acoustic parameters was 85.9 for the six erasons, and the first five principal components could represent 86.3% of the information. The results of three kinds of statistical analysis show that the spectrum energy distribution of friction section is the most important group of acoustic parameters of Putonghua stopper, some of which mainly represent the pronunciation position, some mainly represent the state of gas exhalation; The duration and amplitude of the friction section mainly indicate the state of gas exhalation and the vowels followed by them, and the F _ 2 initial frequency of the posterior vowels is also affected by the location of the impingement sounds.
