本研究通过分析高水平英语学习者和中等水平英语学习者和美国本土英语学习者产生的10个单词对和5个重音转换的单词三元组，考察了日本英语学习者区分重读音节和非重读音节的能力。研究结果如下：首先，Jeh和JEM经常在非重读的音节中产生去声元音，例如cómp[jʊ̥]tátion，这与日语中元音去声的语音环境大致相同。第二，初级重读、次级重读和非重读音节的元音时长和第一共振峰频率在AE、Jeh和JEM之间存在显著差异。JE的次重读音节与非重读音节之间的声学差异小于AE，但JE重读音节与非重读音节之间的声学差异大于AE。总之，JE和AE在英语重音的语音实现上有所不同，表现出母语的影响和困难，存在两个以上的重音水平。
The present study investigated how well Japanese learners of English (JE) can differentiate stressed and unstressed syllables in English, by analyzing ten word pairs and five word triplets that exhibit stress shift, e.g., compúter-còmputátion , produced by high-proficiency (JEH) and mid-proficiency (JEM) learners and native American English speakers (AE). Results were as follows. First, JEH and JEM frequently produced devoiced vowels in unstressed syllables, e.g., còmp[jʊ̥]tátion , approximately in the same phonetic environments where vowels are devoiced in Japanese. Second, vowel duration and first-formant frequencies of primary-stressed, secondary-stressed, and unstressed syllables differed significantly across AE, JEH, and JEM. In particular, the acoustic differences between secondary-stressed and unstressed syllables were smaller for JE than for AE, but those between primary-and secondary-stressed syllables were larger for JE than for AE. Altogether, JE diverge from AE in their phonetic realization of English stress, showing native-language influences and difficulties with more than two stress levels.
