Abstract
ABSTRACT Fluency in terms of speed of speech and (lack of) hesitations such as silent and filled pauses (‘uhm’s) is part of oral proficiency. Language assessment rubrics therefore include aspects of fluency. Measuring fluency, however, is highly time-consuming because of the manual labour involved. The current paper aims to automatically measure aspects of L2 fluency, including filled pauses, in both Dutch and English. A revised existing script and a new script for filled pauses are tested on accuracy. We also gauged whether the outcomes of the new script could be used for language assessment purposes by relating the outcomes to human judgements. Without further investigations, the current script should not (yet) be used for the purpose of assessing fluency automatically in (high-stakes) oral proficiency assessment. However, the performance of the scripts for measuring aspects of fluency globally and quickly are promising, especially given their stability in accuracy on new corpora.
