초록
The purpose of this study was to investigate the role of fluency and rhythm measures on proficiency level in spontaneous English monologues of Korean EFL learners. To this end, an extensive statistical analysis was conducted with 14 measures of fluency and rhythm using a newly developed corpus of 243 English learners to find predictors that have the greatest influence on proficiency levels and examine the relationship between measures. The results show that the three measures of articulation, pause duration, and function word accuracy rate are the most important predictors and, among them, articulation rate is the best predictor, confirming prior studies. Pauses were found to be important not only because they directly affect proficiency assessments, but also because they alter the variability between adjacent intervals. Function word accuracy rate was also able to distinguish between the groups of proficiency levels. This study contributes to uncovering the characteristics of spontaneous speech that are different from read speech and the validity of these measures in assessing L2 speech.
