项目摘要

Some of the phoneme boundaries show complex acoustic characteristics which do not fit with simple psycho-acoustic expectations. Such phoneme boundaries are expected to be especially difficult for the learners of the second language. In the case of Japanese, special moraec phonemes, which are mainly identified thorough durational characteristics, are often difficult for the foreign learners. This study analyzed the perception of the durational characteristics in the identification of these phonemes by the foreign learners and the native speakers of Japanese. In the identification of Japanese long / short vowels, foreign learners showed effects of pitch, intensity and syllable positions while native Japanese did not show such effects. From general psycho-acoustic point of view, it is expected that the pitch and intensity affect the perceptual impression of duration. The native Japanese appears to have special criteria different from naive perception of durational characteristics. In the identification of the single/geminate stop consonants, which is basically based on the duration of the consonant closure, native Japanese subjects showed increased response of geminate identification with the increased duration of the preceding vowel. This result shows that their identification is based on the syllable timing. Above results suggest that the syllable timing other than the simple segment duration plays an important role in the identification of the durational characteristics in these phonemes by the native Japanese.

一些音素边界显示出复杂的声学特征，这些特征与简单的心理声学期望不符。对于第二语言的学习者来说，这种音调边界有望特别困难。对于日本人，特殊的莫拉克音素主要被确定为彻底的持续时间特征，对于外国学习者来说通常很难。这项研究分析了外国学习者和日语的母语者对这些音素识别这些音素的持续特征的看法。在识别日本长 /短元音时，外国学习者表现出俯仰，强度和音节位置的影响，而日本人则没有显示出这种影响。从一般的心理声学角度来看，预计音高和强度会影响持续时间的感知印象。日本人似乎的特殊标准与对持续时间特征的天真感知不同。在鉴定单个/Geminate停止辅音（基本上是基于辅音闭合的持续时间）时，日本本地受试者显示出Geminate鉴定的响应增加，而前面元音的持续时间增加。该结果表明他们的识别基于音节时间。上面的结果表明，除简单段持续时间以外的音节时序在鉴定这些音素的持续时间特征中起着重要作用。
