MiruSinger: A Singing Skill Visualization Interface Using Real-Time Feedback and Music CD Recordings as Referential Data

MiruSinger is a singing skill visualization interface that analyzes and visualizes vocal singing in reference to the vocal-part of music CD recordings. The system focuses on visualizing the characteristics of singing skills with real- time feedback. Although there are previous systems for singing training assistance that provide real-time visual feedback of the singing voice, none had utilized real-world (commercial) recordings as referential data. MiruSinger has the capability of visualizing F0 (fundamental fre- quency) and vibrato sections of the user´s singing voice in real-time, showing comparison with the estimated F0 tra- jectory of the vocal-part in music CD recordings. The ex- tracted F0 trajectory can be hand-corrected to improve ref- erential quality. A trial usage of the system shows that it would be a useful tool for average users, and that the sys- tem itself is entertaining and fun for the users.
