Classical speaker and language recognition techniques can be applied to the classiication of unknown utterances by computing the likelihoods of the utterances given a set of well trained target models. This paper addresses the problem of grouping unknown utterances when no information is available regarding the speaker or language classes or even the total(More)
A method is described for estimating telephone handset nonlinearity by matching the spectral magnitude of the distorted signal to the output of a nonlinear channel model, driven by an undistorted reference. This "magnitude-only"representation allows the model to directly match unwanted speech formants that arise over nonlinear channels and that are a(More)
