Vocalistener2: A singing synthesis system able to mimic a user's singing in terms of voice timbre changes as well as pitch and d

This paper presents a singing synthesis system, VocaListener2, that can automatically synthesize a singing voice by mimicking the timbre changes of a user’s singing voice. The system is an extension of our previous VocaListener system which deals with only pitch and dynamics. Most previous techniques for manipulating voice timbre have focused on voice conversion and voice morphing, and they cannot deal with the timbre changes during singing. To develop VocaListener2, we constructed a voice timbre space on the basis of various singing voices that are synchronized under pitch, dynamics, and phoneme by using VocaListener. In this space, the timbre changes can be reflected in the synthesized singing voice. The system was evaluated by the Euclidean distance in the space between an estimated result and a ground-truth under closed/open conditions.
