This study evaluated the efficacy of remote video-based behavioral skills training (BST) on teaching public speaking behaviors to 4 participants. A multiple-baseline design across speech behaviors was used to evaluate the effects of the training. Remote video-based BST was effective at increasing public speaking behaviors for all participants. In addition, performance generalized to an increased audience size. An external expert in communications rated the participants as more effective public speakers following training. All participants reported satisfaction with the training and expressed greater comfort, confidence, overall ability, and less anxiety as a public speaker following training. We also measured potential collateral effects of teaching public speaking behaviors on speech disfluencies. Although remote video-based BST was effective for all participants, it did not produce a change in the rate of speech disfluencies. Our findings indicate that public speaking behaviors can be taught using a remote video-based BST package.

远程视频培训对公开演讲的效果

本研究评估了基于远程视频的行为技能培训 (BST) 对 4 名参与者进行公开演讲行为教学的效果。使用跨语音行为的多基线设计来评估训练效果。基于远程视频的 BST 有效地增加了所有参与者的公开演讲行为。此外，性能一般化为增加的观众规模。一名外部传播专家将参与者评为经过培训后更有效的公众演讲者。所有参与者都对培训表示满意，并表示在培训后作为公众演讲者更加舒适、自信、整体能力和焦虑更少。我们还测量了教授公开演讲行为对言语不流畅的潜在附带影响。虽然基于远程视频的 BST 对所有参与者都有效，但它并没有产生言语不流畅率的变化。我们的研究结果表明，可以使用基于远程视频的 BST 包来教授公众演讲行为。
