Abstract

The invention provides an automatic marking method for karaok vocal accompaniment. In the method, pitch, beat position and volume of a singer are compared with the original pitch, beat position and volume of the theme of a song to generate tone sensation score, rhythm sensation score and emotion score respectively, so as to obtain weighted total score in a weighted marking method.
