Pitch-based musical performance scoring for a PC-based karaoke system

Proceedings of the Eleventh OU-DLSU Academic Research Workshop
Karaoke has grown to be a nationwide amusement. However, standard karaoke machines nowadays lack accurate, interactive and easily comprehensible way of analyzing and critiquing vocal signals. In this paper we propose a study which integrates the general concepts in music with theories and techniques in digital signal processing to produce justified criteria for judging a singer's musical accurateness and tonality through the use of time-frequency analysis tools. Analysis of the singing voice was accomplished by applying a short-time discrete Fourier transform for variable time frames of voice data which was based on the onset times and durations of notes from the reference melody, and by developing a technique in extracting the fundamental frequency component of each voice segment, which contains the pitch for the specific time frame. A scoring platform was developed using a certain criteria, which is geared toward fair judging and proves an improvement with that of the scores given by popular karaoke systems.
