Lending a hand to speech: Gestures Help Fluency and Increase Pitch in Second Language Speakers

This study examines the effect of gestures on second language (L2) pitch measures and fluency in storytelling tasks. It is well documented that L2 learners commonly use gestures in conversations and storytelling. Research has shown that gestures benefit L2 word learning and recall, but it is still unclear to what extent gestures affect speech fluency and pitch range. We compared a series of speech fluency and pitch measures across two storytelling tasks: task repetition and explicit instruction on the use of gestures. By analysing the use of gestures in these tasks, we provide insights on how gestures can help L2 fluency and intonation.
