摘　　要：汉语普通话元音一共有10个,其中/a,o,γ,i,u,y/六个元音的听辨线索已经被发现。而元音//的声学性质与/y/很接近,因此,二者的听辨线索就成为语音感知上的重要问题。本文通过一系列辨识和评价实验,研究汉语元音//的兴奋模式与其语音性质的关系,以此确定该元音的听辨线索。实验结果表明://的语音性质是由其第二兴奋模式峰位置决定,与其他兴奋模式峰无关(如果存在的话)。这与/y/的听辨线索是相同的,且其兴奋模式峰的位置也与/y/的比较靠近,这就解释了为何二者在很多听闻条件下容易被混淆的原因。Chinese mandarin has 10 vowels, and the perceptual cue of/a,o,~,i ,u,y/has been discovered./ι/is similar to/y/in acoustical properties, so it is important thing that distinguish the perceptual cue of/ι/ from/y/. The relationship between excitation pattern and acousticaX properties of/ι/ has been researched in this article through a series of identification and evaluation experiments to discover the perceptual cue of/ι/. It is showed that the acoustical properties of/ι/is decided by position of the second excitation pattern peak and has nothing to do with other excitation pattern peaks（ if exist） in this experiment. The perceptual cue of/3/is the same as/y/, and the positions of their excitation pattern peaks is near. This explains why they are easy to be confused in many listening conditions.
