The relationship between perception and production in L2 English stress acquisition

다국어 초록 (Multilingual Abstract)

This paper investigated whether L2 learners’ pronunciation difficulties were related to their perceptual deficiency of the target sounds, by conducting experiments on 29 Korean learners’ acquisition of English word stress. It was shown that overall the correct percentage of perception (76.83%) was significantly higher than that of production (55.93%). However, there was no correlation between perception and production, which suggests that second (or foreign) language learners’ good perception abilities do not necessarily reflect their good production abilities, and vice versa. It was also shown that the overall results interacted with suffix class (class 1 or class 2) and lexical class (noun or adjective). Specifically, the participants performed much better with class 2 suffixes (perception 85.4%; production 73.5%) than with class 1 suffixes (perception 68.3%; production 38.4%) across perception and production. As for lexical class, the participants were more likely to perceive main stress target-appropriately when the target words were adjectives than when they were nouns (noun 74.6% vs. adjective 79.1%). However, their production of primary stress was more target-appropriate when the target words were nouns than adjectives (noun 63.8% vs. adjective 48.1%). More specifically, the participants had most difficulty in producing correct stress when the targets were class 1 adjectives, followed by class 1 nouns. The participants’ perception and production error patterns were also analyzed in terms of the number of errors and the distribution of syllable position. Based on the findings of the study, some pedagogical implications for the teaching of English word stress were drawn.
