公众演讲焦虑的多模态表征及其对大学英语演讲教学的启示

Multimodal Representation of Public Speaking Anxiety and Its Implications for College English Speech Teaching

摘要: 通过梳理国外公众演讲焦虑的进展与实证研究，发现目前研究主要聚焦在公众演讲焦虑的原因、评估和缓解办法的探究上。多数研究虽有提及公众演讲焦虑表征，但对其多模态表征方面缺乏详细系统的讨论。基于对相关文献中公众演讲焦虑多模态表征的分析，本研究发现其言语表征主要体现在语音不流畅、停顿等，而非言语表征则主要有身体摆动、双手紧握、呼吸不畅等。这些结果表明有必要利用多模态传感技术提取与分析大学英语公众演讲者焦虑的多模态特征，并借助虚拟现实技术对其进行干预，以降低中国大学英语演讲者的焦虑水平；通过英语演讲课程常态化来全面提升我国大学英语演讲教学的有效性和普及性。

Abstract: By reviewing the progress and empirical research on public speaking anxiety in foreign countries, it has been found that current research mainly focuses on exploring the causes, evaluation, and miti-gation methods of public speaking anxiety. Although most studies have mentioned the representa-tion of public speaking anxiety, there is a lack of detailed and systematic discussion on its multi-modal representation. Based on the analysis of multimodal representations of public speaking anx-iety in relevant literature, this study finds that their verbal representations of public speaking are mainly embodied in speech disfluency, pauses, etc., while nonverbal representations are mainly re-flected in body swings, clenched hands, breathing difficulties, etc. These results indicate the neces-sity of utilizing multimodal sensing technology to extract and analyze the multimodal characteris-tics of anxiety among college English public speakers, and intervening with virtual reality technol-ogy to reduce the anxiety of Chinese college English speakers. Through the normalization of English speech course, the effectiveness and popularity of college English speech teaching in China are comprehensively improved.
