Abstract

This study investigated the production of English unstressed vowels by Japanese speakers based on the J-AESOP corpus. Four acoustic features associated with unstressed vowels in English were examined: duration, intensity, fundamental frequency and vowel quality. Comparative analysis with native English speakers' production revealed that the Japanese speakers achieved good control of all the acoustic features except vowel quality, supporting the results of previous studies. Their attainment of nearnative control of duration, intensity and fundamental frequency can be attributed to positive L1 transfer from Japanese. As for vowel quality, the present study showed that the quality of the Japanese speakers' unstressed vowels was more peripheral than that of the native English speakers' because of the difficulty of L2 phoneme acquisition and the influence of orthography.

用J-AESOP语料库研究日本人说英语的非重读元音的产生

本研究基于J-AESOP语料库调查了日本人英语非重读元音的产生。研究了英语中与非重读元音相关的四个声学特征:持续时间、强度、基本频率和元音质量。与以英语为母语的人的发音进行对比分析发现，日语使用者对除元音音质外的所有声学特征的控制都很好，这支持了之前的研究结果。他们对持续时间、强度和基频的接近本地控制可以归因于日语的积极母语迁移。在元音质量方面，本研究表明，由于二语音素习得困难和正字法的影响，日语母语者的非重读元音质量比英语母语者更为次要。
