项目摘要

Vowel epenthesis is a well known phenomenon that non-native speakers insert epenthetic vowels inside non-native consonant clusters. Vowel epenthesis is assumed as perceptual "illusory vowels" (Dupoux, et al. 1999). We analyzed vowel epenthesis shown by native Japanese speakers during reading and repetition tasks for non-native consonant clusters, and analyzed their brain responses using magnetoencephalographic methods. Under the reading task, in which subjects read English words and nonsense words, native Japanese speakers inserted vowel /o/ after /t/ and /d/ in consonant clusters, and vowel /u/ after other consonants. Under the repetition task, in which subjects repeated utterances of a native English speaker, native Japanese speakers did not produce epenthetic vowels, with a few exceptions. The length of exceptional epenthetic vowels found under the repetition task was shorter than those under the reading task. The magnetoencephalographic mismatch responses were elicited by epenthetic vowels, suggesting that the native Japanese detected epenthetic vowels as real segments. Based on these results, we conclude that vowel epenthesis by native Japanese speakers did not arise from "illusory vowels", but rather from the difficulty of articulating consonant clusters which are not found in Japanese, and/or Japanese phonological rules.

元音元素是一种众所周知的现象，即非本地扬声器在非本地辅音簇中插入静脉元音。元音元素被认为是感知的“虚幻元音”（Dupoux等，1999）。我们分析了日本母语者在阅读和重复任务的非本地辅音簇中显示的元音元素，并使用磁脑摄影方法分析了他们的大脑反应。在阅读任务下，受试者阅读英语单词和废话单词，日语母语者在辅音簇中插入元音 / o / o / aft / t / and / d / d / d / d / d / d / d / vowel / u /在其他辅音之后。在重复任务下，在该任务中，主语是英语英语的人，日本母语人士并没有产生简单的元音，但少数例外。在重复任务下发现的异常元元音的长度比阅读任务下的长度短。磁脑遗传不匹配的响应是通过元素元音引起的，这表明日本本地原住民将静脉元音视为实际段。基于这些结果，我们得出结论，日本母语人士的元音元素不是来自“虚幻元音”，而是源于表达辅音簇的困难，而这些辅音簇在日语和/或日本语音学规则中都找不到。
