Singing performance evaluation by reference to CD music recordings

This paper proposes an automatic system that rates a singing performance by comparing it with the vocal pitch in a referential CD music recording. The system allows users to not only enjoy listening to and singing with CD songs but also know how well or bad they sing. To this end, our special efforts are put on extracting the pitch-based features of the original singer in the accompanied vocals. Our experiment shows that the results of the proposed singing evaluation system are close to the human rating.
