Public Speaking Enhancement via Virtual Reality

摘要

In this paper I proposed the one of a kind way to deal with the dread of speaking publically (Gloss fear) using Virtual Reality (VR) and Audio Signal preparing. The framework is planned on Unity3D (a Game Development Engine) and it utilizes the ideas and Algorithms of Digital Signal Processing to outline a Native Audio Plugin for Unity3D which can be utilized to analyze Audio Signals. The VR Simulator records a reference audio from the user and compares the user's execution with respect to the Audio input got from the user in a Virtual talking condition. The discourse/ speech correlation and coordinating of the two Audio Signals is finished using speaker verification algorithm using Spectrogram. Pause detection algorithm estimates level of familiarity with discourse/ speech. Additionally, eye contact of the user with group of onlookers is checked using Ray Caster in Unity3D. The mix of the outcomes abridged together creates a score which causes the user to enhance his/her aptitudes of public speaking.
