This paper presents a novel graph-based approach for solving a problem of fast finding a speech model acoustically similar to a query model from a large set of speech models. Each speech model in the set is represented by a Gaussian mixture model and dissimilarity from a GMM to another is measured with a Kullback-Leibler divergence (KLD). Conventional pruning techniques based on the triangle inequality...
In this paper, we describe a parametric mixture model for modelling the resonant characteristics of the vocal tract. We propose a mixtures of Gaussians (MoG) spectral modelling scheme which enables model selection with a goal of easing the correspondence between the resonant characteristics of the vocal tract and the parametric Gaussians and representing a spectrum with an appropriate number of parameters...
