A Comparative Study of Fluency Acquisition and Ratings for English and Korean L2 learners: focused on subjects’ L2 residence experience

This study examined the effect of second language (L2) immersion experience on adult’s acquisition of fluency factors (speech rate, F0 range, pause duration and frequency, hesitation duration and frequency). Nineteen Korean learners of English and English learners of Korean who divided into two timing positions of L2 immersion experience (t1 = 1 month, t2 = 6 month) produced 1 paragraph as a way of a sentence repetition task and were recorded. Thirteen English natives and Korean native raters were invited to determine how fluently the subjects produced and to what extent they contributed to the fluency rate. Results indicated that the effect of L2 experience had more effect on English learners of Korean than on Korean learning English, even though Korean learners of English achieved higher scores of fluency. In the perception test, the factors of speech rate and pause duration were found to influence more on the fluency judgement cross-linguistically. The comparatively wide difference between two target languages, however, were found in the pitch range and the hesitations. The study indicated that process of L2 acquisition has involved the universal as well as language-specific features.
