We have previously proposed a statistical model of speech F 0 contours, which is based on the discrete-time version of the Fujisaki model.One advantage of this model is that it allows us to introduce statistical methods to learn the Fujisaki-model parameters from speech F0 contours.This paper proposes several modifications to our previous model and parameter inference algorithm, and quantitatively evaluates the performance of our modified parameter inference algorithm.
