Oral fluency in the narrow sense usually measures temporal variables and dysfluency pausing variables. Currently the mainstream paradigm of L2 empirical researches is to measure oral fluency through temporal variables. The purpose of this study is to compare the correlation coefficients between Chinese learners’ temporal variables, pausing variables and their oral production scores. The subjects of the study are 45 contestants from a National College English speech contest. It is found that although the five temporal variables are significantly correlated with the holistic scores of the contestants, the frequency and duration of pauses at non-clause boundaries have higher correlation coefficients with the holistic scores of the contestants. The findings help to improve quantitative analysis of oral fluency.
