  Stress during public speaking is common and adversely affects performance and
self-confidence. Extensive research has been carried out to develop various
models to recognize emotional states. However, minimal research has been
conducted to detect stress during public speaking in real time using voice
analysis. In this context, the current review showed that the application of
algorithms was not properly explored and helped identify the main obstacles in
creating a suitable testing environment while accounting for current
complexities and limitations. In this paper, we present our main idea and
propose a stress detection computational algorithmic model that could be
integrated into a Virtual Reality (VR) application to create an intelligent
virtual audience for improving public speaking skills. The developed model,
when integrated with VR, will be able to detect excessive stress in real time
by analysing voice features correlated to physiological parameters indicative
of stress and help users gradually control excessive stress and improve public
speaking performance
