普通话元音/a/和/█/的听感边界初探

A Study on Perceptive Boundary between/a/&/█/in Mandarin

文章以普通话元音/a/和/?/为研究对象,通过辨认实验和区分实验,探索单字音中/a/和/?/的听感边界,并尝试从调类、测试界面正反序以及性别等角度进一步探究影响听感边界的因素。实验结果表明,普通话/a/和/?/的听感边界是动态的,边界处F1值为600—682Hz,最小值在阳平,最大值在去声。同时,测试界面正反序和性别因素对其边界位置都有一定的影响,整体上反序的边界值大于相应的正序,女生的边界值大于相应的男生。对单字音中/a/和/?/听感边界的考察是探索普通话元音孤立感知格局的重要组成部分。

The experiment is designed to study/a/&/?/in monosyllable of standard Chinese and examine the perceptive boundary between/a/&/?/by adopting identification and discrimination tests.The study also tries to find the factors in affecting the boundary position through tones,the displaying orders of options and genders.The results show that the perceptive boundary between/a/&/?/is dynamic,and the value of F1 between 600-682 Hz,with the minimum value in Rising Tone,and the maximum value in Falling Tone.At the same time,the displaying orders and genders also play significant roles in affecting the perceptive boundary positions.As a whole,the boundary value of the antitone sequence is higher than that of the corresponding positive sequence,and the female's boundary value is more than the male's.This study is a part of an isolated perceptive pattern of vowels in Mandarin.
