Voice conversion involves transforming segments of speech from a source speaker to make them to be perceived as if spoken by a target speaker. Generally, this process involves the estimation of vocal tract parameters and an excitation signal that match the target speaker. The work presented here proposes an algorithm for estimating the excitation residuals of the target speaker using a weighted...

If a data set suffers from selection bias then, ordinary regression estimators must be adapted in order to achieve consistency. Consequently, it is necessary to modify any goodness of fit tests based on distances between parametric and non-parametric residuals. More particularly, any bootstrap approximation to these tests must be re– designed. Our first approach to this latter task is based on ...

We obtain analytic solutions of the model problem stationary heat conduction for a composite plate. These are constructed with help two methods aimed at reducing dimensionality, namely, method weighted residuals (the generalized Galerkin method) and variational method. consider homogeneous rectangular elongated plate made an anisotropic material in general form. The front faces structure therma...

We consider nonlinear and heteroscedastic autoregressive models whose residuals are martingale increments with conditional distributions that fulfill certain constraints. We treat two classes of constraints: residuals depending on the past through some function of the past observations only, and residuals that are invariant under some finite group of transformations. We determine the efficient ...

This paper considers residual-based and randomly weighted kernel estimators for innovation densities of nonlinear autoregressive models. The weights are chosen to make use of the information that the innovations have mean zero. Rates of convergence are obtained in weighted L1-norms. These estimators give rise to smoothed and weighted empirical distribution functions and moments. It is shown tha...

The solution of integropartial differential equations resulting from statistical formulations of the behavior of cell populations has been investigated. In particular, a statistical model that views the microbial population as distributed according to its mass has been analyzed in detail. Solutions were obtained for growth in a well-stirred vessel for batch and continuous systems by the method ...
