声音进入外围听觉系统以后会经历很多变化.激励模式(excitation pattern)是指从心理声学的角度给出的经历了这样的变化后的声音的内部表达式.本文研究了汉语稳态元音的激励模式与其语音性质之间的关系.首先,在一个语料库上测量了激励模式的包络峰,结果显示这些汉语元音每个都有自己独特的峰位置.然后,为了检验激励模式峰位置对元音性质(vowel quality)知觉的充分性,设计了一系列辨识和评价实验.其中实验刺激是经过特殊的滤波处理改变了原有激励模式的自然孤立发音的汉语单元音.被试对刺激信号的反应显示元音的激励模式的特定包络峰位置对其语音性质起到决定性作用.这些结果表明,这些元音的语音性质由其激励模式的特定峰的位置决定,与激励模式的其他峰无关(如果存在的话).最后,基于本文结果对一些言语知觉现象进行了解释.
Sound enters the peripheral auditory system after going through many changes.Encouraging mode (excitation pattern) refers to the psycho-acoustics point of view of the voice after experiencing such a change in the internal expression.This paper studies the Chinese steady vowel excitation Model and its phonetic properties.Firstly, the enveloping peaks of excitation modes were measured on a corpus, and the results show that each of these Chinese vowels has its own unique peak position.Then, in order to test the peak position of excitation modes, A series of experiments were conducted to identify and evaluate vowel quality, in which experimental stimulation was a special filter processing to change the natural vocal isolated Chinese phonetic sounds of original excitation mode. The response shows that the specific envelope location of the vowel excitation pattern is decisive for its phonetic properties.These results show that the phonetic properties of these vowels are determined by the location of a particular peak in their excitation pattern and not by the other peaks in the excitation pattern (If any) .Finally, some speech perceptions are explained based on the results of this paper.
