In this thesis, a real time singing scoring system based on virtual reality technology is proposed. When a user sings a song, the system will analyse and process the user’s audio, compare it with the standard audio, give the corresponding score and change the character animation in the scene in real time according to the score level. By giving the user a visually realistic experience, the system creates desensitisation, thus reducing the user’s fear of performing on stage and improving their ability to perform on stage.
