Pause position analysis in spontaneous speech for L2 English fluency assessment

L2英語流暢性評価のための自然発話におけるポーズ位置分析

Résumé

When learning a foreign language, fluency is often considered a key characteristic for being easily understood by listeners. To assess fluency in a spontaneous speech situation, automatic tools typically deal with the frequency and mean duration of silent and filled pauses, but pauses are is not necessarily a problem, rather, they should make speech more comprehensible. It can, however, be detrimental when they occur in unexpected positions. We present a fully automated pipeline for identifying pause positions at both the phrase (syntactic structure) and lexical levels (part of speech of surrounding words). Analysis of 177 L2 English learners has shown that pause position varies greatly from one student to another, and should be better taken into account when assessing speaking.
