项目摘要

1.Durational pattern of Japanese stops produced by the foreign learners of Japanese.Duration of the stop consonants in the 3-morae words were analyzed. For the French subjects, ratios of the closure period + VOT relative to the word duration were dose to that by native Japanese For the Americans and Chinese, the ratios were greater and their productions were often perceived as Sokuon (geminate) by native Japanese.2.Identification of Japanese single consonants and Sokuon (geminate).The test words were the 2-syllable words. For the Spanish subjects, the error rate was low both for the single consonant and geminate. The Korean subjects showed remarkably higher error rate for the identification of single consonants in the test words of the High-Low accent. The Thai subjects showed high error rate for the single consonants both in the High-Low and Low-High accent words.3.Identification of the long and short vowels.The test words were 2-syllable words. Korean and Thai subjects generally showed higher error rate in identifying long vowels than short vowels. Error rate was especially high when the long vowels were located in the word final position and the pitch was low.4.Acoustic factors affecting the perception of the long-and short vowels.Perceptual experiments were conducted with the Korean subjects and the Japanese subjects to compare the acoustic factors affecting the perception of the sound duration. The identification and discrimination of the duration of the pure tones and the vowel sounds were examined. In the discrimination tests, both the Korean and the Japanese subjects showed the influence of the pitch and intensity of the stimulus sounds. However, in the identification of the long and short vowels, only the Korean subjects showed an influence of the pitch and intensity. It was confirmed that the Japanese has a timing perception based on the purely durational characteristics.

1.外国日语学习者的日语塞音的时长模式，分析了三个音节词中塞音的时长。法国受试者的闭合期+ VOT占词时长的比例与日本本土受试者的相似。美国受试者和中国受试者的闭合期+VOT占词时长的比例较大，其产出在日本本土受试者看来往往是Sokuon（成对）。对于西班牙语的主题，错误率是低的单辅音和双辅音。朝鲜族被试在高低音测试词中对单个辅音的识别错误率显著高于其他民族。泰国被试在高低重音词中对单辅音的识别错误率较高。3.长短元音的识别。韩语和泰语被试在识别长元音时的错误率普遍高于短元音。当长元音位于词尾位置且音高较低时，错误率尤其高。4.影响长短元音感知的声学因素通过对韩国人和日本人的感知实验，比较了影响长短元音感知的声学因素。对纯音和元音的音长进行了识别和区分。在辨别测试中，韩国和日本的受试者都表现出刺激声音的音高和强度的影响。而在长短元音的识别中，只有韩国人表现出音高和强度的影响。结果证实，日本人具有基于纯粹持续特征的时间知觉。
