A study on coordination between gesture and speech from the viewpoint of speech mechanism

本研究的重点是言语和手势之间的联系，手势是用手对概念的标志性表示。更具体地说，它研究了两个模块在语音产生过程中是独立运行还是通过相互监控而相互连接。在实验中，讲话者在进行描述任务时，他们的手被固定在一块板上，因此不能动（手势限制条件），而手的运动没有限制（自由手势条件）。研究人员检查了语音流利度、拟声词的频率和语音质量，看看它们是否会随着手的可用性而变化。

The present study focuses on the link between speech and gesture which is iconic representation of concepts with hands. More specifically, it investigates whether the two modules operate independently during speech production or they are interconnected through mutual monitoring. In the experiment, speakers engage in a description task while their hands are attached to a board and thus immobile (gesture restriction condition) and while there is no restriction on hand movements (free gesture condition). Speech fluency, frequency of onomatopoetic words, and voice quality were examined to see if they vary according to the availability of hands.
