Abstract
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.
Résumé
Cette étude examine l’effet des gestes sur le registre tonal et la fluidité en L2 dans des tâches narratives. Il est bien connu que les apprenants d’une L2 utilisent couramment des gestes dans les conversations et les récits. La recherche a montré que les gestes favorisent l’apprentissage et la mémorisation des mots en L2, mais on ne sait toujours pas dans quelle mesure ils affectent la fluidité et la hauteur tonale en L2. Nous avons comparé la fluidité de la parole et le registre tonal dans deux types différents de narration : la répétition et l’instruction explicite sur l’utilisation des gestes. En examinant l’impact des gestes sur ces deux tâches, nous donnons un aperçu de la façon dont les gestes peuvent contribuer à améliorer la fluidité et le registre tonal en aider la L
