| Research Abstract |
Unlike solo singing, singing behavior in a chorus is affected by other singers, therefore, acoustical characteristics may differ from that of solo singing. Such interaction between singers in a chorus is analyzed from the view point of ‘entrainment’ in singing behavior. As the first step, a model of F0 dynamics, i.e., the dynamic properties of fundamental frequency of singing voices in chorus is studied. The model parameters are estimated using a steepest decent method. The characteristics of the F0 dynamics of a voice singing in a chorus are parameterized. Preliminary experiments also show that experienced and novice singers can be correctly identified using the parameters of our model, because their entrainment behaviors are significantly different. It is confirmed that the our model can properly characterize individual singers by analyzing F0 entrainment during chorus singing.
