ABSTRACT:
A performance evaluation method for use in a karaoke apparatus evaluates a singing performance of a karaoke singer by measuring differences between the karaoke singer's vocal rendition and an accompanying music produced by an audiovisual device. Digitized voice signals and their corresponding digitized accompaniment signals are produced by sampling simultaneously the karaoke singer's vocal rendition and the accompanying music, respectively. Then, a difference between a digitized voice signal and its corresponding digitized accompaniment signal and a trend of differences are calculated and used to generate a performance score.
