“…In the context of public speaking training, some studies have tested the use of VR technology to reduce anxiety in university students. In a systematic review, Daniels et al (2020) identified 14 studies conducted from 2009 to 2019 that used VR as a tool to diminish public speaking anxiety (PSA). From these 14 studies, 7 belonged to clinical settings (Wallach et al, 2009(Wallach et al, , 2011Lister et al, 2010;Lister, 2016;Lindner et al, 2018;Yuen et al, 2019;Zacarin et al, 2019).…”

Public speaking is fundamental in our daily life, and it happens to be challenging for many people. Like all aspects of language, these skills should be encouraged early on in educational settings. However, the high number of students per class and the extensive curriculum both limit the possibilities of the training and, moreover, entail that students give short in-class presentations under great time pressure. Virtual Reality (VR) environments can help speakers and teachers meet these challenges and foster oral skills. This experimental study employs a between-subjects pre- and post-training design with four Catalan high-school student groups, a VR group (N = 30) and a Non-VR group (N = 20). Both groups gave a 2-min speech in front of a live audience before (pre-training) and after (post-training) 3 training sessions (one session per week) in which they practiced public speaking either in front of a VR audience or alone in a classroom (Non-VR). Students assessed their anxiety measures right before performing every speech and filled out a satisfaction questionnaire at the end. Pre- and post-training speeches were assessed by 15 raters, who analyzed the persuasiveness of the message and the charisma of the presenter. Speeches were also analyzed for prosodic features and gesture rate. First, results showed that self-assessed anxiety got significantly reduced at post-training for both conditions. Second, acoustic analyses of both groups' speeches show that the VR group has, unlike the Non-VR group, developed a more clear and resonant voice quality in the post-training speeches, in terms of higher cepstral-peak prominence (CPP) (although no significant differences in f0- related parameters as a function of training were obtained), as well as significantly less erosion effects than the Non-VR group. However, these differences across groups did not trigger a direct improvement on the participants' gesture rate, persuasiveness and charisma at post-training. Furthermore, students perceived the training in the VR environment to be more useful and beneficial for their future oral presentations than the Non-VR group. All in all, short unguided VR training sessions can help students feel less anxious, promote a more clear and resonant voice style, and can prevent them from experiencing an erosion effect while practicing speeches in front of a real audience.

“…This knowledge may be helpful in training public speakers as symptoms of PSA can be triggered by VR training and thus, enabling public speaking simulation. Furthermore, according to Wallach et al (2009) or Daniels et al (2020), VR can help reduce this anxiety too and thus we imply that virtual worlds are used to reduce PSA by using the stimuli identified in this study.…”

“…Meta-analysis (Reeves et al, 2021a) and systematic literature reviews (Daniels et al, 2020) support these findings. Cognitive behavior therapy (CBT) and virtual reality exposure therapy (VRET) help treat PSA (Daniels et al, 2020). Daniels et al (2020) even highly recommended the use of VR to treat PSA and reported reduction of PSA levels ranging from 7.8 % up to 54.7 %.…”

Using Virtual Reality Simulation to Reduce Stage Fright During Public Appearances

Past applications of virtual reality (VR) and related research have provided evidence that VR technology is helpful for educational and training purposes and that it can be used as a therapeutic measure. Virtual reality exposure therapy (VRET) may, therefore, be beneficial in reducing public speaking anxiety (PSA), which is a very common phenomenon. In this preliminary study, we conducted an experiment to investigate the psychological and physiological response to stressors experienced when speaking in public by creating a virtual audience displaying worst-case-scenario behavior (gossiping, shaking their heads, pointing at the speaker, standing up, and even leaving the room). In addition, other potential stressors were introduced (standing on an elevated platform, jumping off the platform, blocking someone's path, approaching a door that opens automatically, and throwing objects). To measure the responses of participants to these stimuli, we asked them to complete a questionnaire and monitored their heart rate. Our findings suggest that people's anxiety increases when they interact with other people in a virtual world, and when they are exposed to certain stimuli, which may be reduced with the repeated application of VRET.
