This paper proposes a stochastic model of speech F0 contours, based on the stochastic formulation of the Fujisaki model. Our motivation for the stochastic formulation is twofold. Firstly, it allows us to derive a well-behaved algorithm for estimating the Fujisaki model parameters from a raw F0 contour. Secondly, it will open the door to incorporating the well-founded F0 contour model into various statistical speech processing problems. We quantitatively evaluated the performance of our method in terms of an Fujisaki-model parameter estimation accuracy using real speech data. Experimental results revealed that our method was superior to a state-of-the-art Fujisaki model parameter extractor.
