Experimental research on the speciality of Japanese in listening to speechsounds.

这项研究旨在回答这个问题，“为什么日本人不善于理解母语人士所说的话？”针对这个问题进行了几次听觉和视听实验。结果如下：1。日语听众认为英语元音/i/、/epsilon/和/a/与日语元音/i/、/e/和/a/.2对应。在日语典型元音/i/、/e/和/a/ 3附近存在刺激顺序效应。英语元音/I/周围不存在刺激顺序效应，日语元音音位系统中不包含刺激顺序效应。4 .将典型元音置于歧义元音之后的刺激顺序效应大于将典型元音置于歧义元音之前的刺激顺序效应。在视听呈现下，元音偶然效应的发生受元音环境的影响，即当辅音-元音（CV）音节由C-/u/组成时，元音偶然效应很少，而当CV音节由C-/i/或C-/a/组成时，元音偶然效应很大。这些结果主要基于母语原型假设、听觉和语音记忆特征以及听觉和视觉信息的整合进行了讨论。

This research ams at answering the question, "Why are the Japanese people bad at understanding what the native speakers say? " Several auditory and audio-visual experiments were conducted on this question. The results are listed below.1. The Japanese listeners perceived the English vowels /i/, /epsilon/, and /a/ corresponing to the Japanese vowels /i/, /e/, and /a/.2. The stimulus order effects were obtained near the typical Japanese vowels /i/, /e/, and /a/.3. The stimulus order effects were not obtained around the English vowels /I/, which is not contained in the Japanese vowel phonemic system.4. The amount of stimulus order effect was greater when typical vowel was put after the ambiguous vowel than when it was put before the ambiguous one.5. Under audi-visual presentation, the occurrence of vowel contingent effect was influenced by the vowel environment-- that is, when the consonant-vowel (CV) syllable was consisted of C-/u/, there were few vowel contingent effects, although the CV sylable was consisted of C-/i/ or C-/a/, there were great vowel contingent effects.These reslts were discussed maily based on the hypotheses of prototypes of native language, the characteristics of auditory and phonetic memory, and the integration of auditory and visual information.
