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.
