초록
This study investigated hyperarticulated, clear speech production of English stress by second language speakers of English. The results of the experiment revealed that second language learners can, to some extent, control their production and that they may have targets for stress production that are undershot but may be reached with more articulatory effort. This suggests that learners regulate phonetic variation in their second language in much the same way as they do for a first language and that when they devote enough attentional resources, they may approximate more native-like productions of specific acoustic features. Three of the acoustic correlates of English stress investigated, i.e., pitch, intensity and duration, were enhanced in clear speech with the exception of duration for Japanese bilinguals. However, vowel reduction in unstressed vowels did not change in clear speech, indicating that it may not be present in learners’ target representations.
Abstract
This study investigated hyperarticulated, clear speech production of English stress by second language speakers of English.

This suggests that learners regulate phonetic variation in their second language in much the same way as they do for a first language and that when they devote enough attentional resources, they may approximate more native-like productions of specific acoustic features. Three of the acoustic correlates of English stress investigated, i.e., pitch, intensity and duration, were enhanced in clear speech with the exception of duration for Japanese bilinguals. However, vowel reduction in unstressed vowels did not change in clear speech, indicating that it may not be present in learners’ target representations.
