基于EGG信号的安多藏语元音嗓音特征研究

以藏语安多方言中极具代表性的夏河话为研究对象,利用Real-TimeEGG分析软件提取了元音/a/、/e/、//、/o/的嗓音参数基频.开商和速度商,并分元音单独出现、带前置辅音、带辅音韵尾和前后都带辅音4种情况进行了讨论.结果表明:3个参数之间有很强的关联性,各种组合方式下前置辅音对嗓音参数的影响不及辅音韵尾的影响程度,当元音前后均接辅音时两者共同作用来影响其嗓音参数.元音之间由于组合方式变化对参数影响趋势基本一致,变化幅度均为元音/e/最大,/o/最小.

Research of Vowel Voice Characteristic in Anto Tibetan Based on EGG Signal

This article take Tibetan Anto dialect in Xiahe words as the object of study,use Real-Time EGG analysis software obtaining the voice parameter pitch,the open quotient and the speed quotient of vowel /a/,/e/,//,/o/,and divide four kinds of situations to carry on the discussion,they are:the vowel to present individually,the consonant front,the consonant behind and the consonant around.The result indicated:3 parameters has the very strong relatedness between each other,under each combination way,the influence of the consonant front on voice parameter is less than the consonant behind,when the consonant around the vowel to affect its voice parameter together,the tendency of influence on parameter is unanimous because of changeable combination way of vowel.the changing scope is vowel/e/is biggest,/o/is smallest.
