本研究考察了美国英语学习者和日本英语学习者对持续时间模式的产生和感知。生产实验表明，美国人和熟练说英语的日语人在增加非重读音节时，通过压缩重读元音来控制重读间隔的持续时间。然而，那些不会说日语的人，几乎没有表现出脚部水平的缩短。知觉实验表明，不熟练的日语在区分重读元音的时长方面并不比美国人更敏感。然而，与美国人相比，他们对重读元音自然发音的判断跨越了更广泛的元音持续时间范围。此外，在美国听者中，以下非重读音节的时长调整补偿了重读元音的延长，而在日语听者中则不能。这些结果表明，ISI在美国人的英语产出和感知中是一个时间单位，但对于不熟练的日语使用者则不是。
This study examines the production and the perception of durational patterns by Americans and by Japanese learners of English. The production experiment demonstrated that the Americans and the proficient Japanese speakers of English control the duration of an interstress interval (ISI) by compressing the stressed vowels when unstressed syllables are added. The non-proficient Japanese speakers, however, showed very little foot-level shortening. The perception experiments demonstrated that non-proficient Japanese are not less sensitive than the Americans in discriminating the durations of stressed vowels. However, their judgments of what is natural for a stressed vowel span a broader range of vowel durations than for the Americans. Moreover, a durational adjustment in the following unstressed syllable compensated for the lengthening of the stressed vowel in the case of the American listeners, but not in the case of the Japanese listeners. These results indicate that the ISI is a temporal unit in the production and the perception of English for the Americans, but not for the non-proficient Japanese speakers.
