This study evaluated the efficacy of (a) remote video-based behavioral skills training (BST) with added speech outlines on teaching public speaking behaviors and (b) remote video-based awareness training (AT) on speech-disfluency rates. A multiple-baseline design across speech behaviors was used to evaluate the training. Remote video-based BST and AT were effective at teaching public speaking behaviors and reducing speech disfluencies, respectively, for both participants. In addition, performance generalized to increased audience size. Although expert ratings of perceived public speaking effectiveness improved following BST, the ratings did not improve and some worsened following AT. Both participants reported satisfaction with video-based BST and AT. One participant reported greater comfort, confidence, overall ability, and less anxiety as a public speaker following BST. Both participants reported greater improvements in those categories following AT. Our results suggest that public speaking behaviors can be taught using remote video-based BST and speech disfluencies can be reduced using remote video-based AT.

基于远程视频的行为技能培训和意识培训对公共演讲表现的功效

本研究评估了（a）基于远程视频的行为技能培训（BST）以及添加演讲大纲的公开演讲行为教学和（b）基于远程视频的意识培训（AT）对言语不流利率的效果。使用跨言语行为的多基线设计来评估训练。基于远程视频的 BST 和 AT 分别能够有效地教导参与者的公开演讲行为和减少言语不流畅。此外，表演也随着观众规模的增加而扩大。尽管 BST 后专家对公众演讲有效性的评分有所提高，但 AT 后评分并没有提高，有些甚至还恶化。两位参与者都对基于视频的 BST 和 AT 表示满意。一名参与者表示，在 BST 之后，作为一名公共演讲者，更加舒适、自信、整体能力提高，焦虑也减少。两位参与者都报告了 AT 之后这些类别的更大进步。我们的结果表明，可以使用基于远程视频的 BST 来教授公开演讲行为，并且可以使用基于远程视频的 AT 来减少言语不流畅。
