Abstract

In this paper a method for Voiced/Unvoiced classification of segments of a speech signal is presented. For this purpose, on each segment four different measurements are made. On the basis of such measurements the a posteriori probabilities of the two classes are determined and the decision is made by means of the maximum a posteriori probability criterion. The a priori probabilities of the classes are updated for each segment. In this context, it is assumed that the sequence of the classes constitutes a 1st order time-omogeneous Markov chain. The experimental result of the method, included in the paper, have been satisfactory.
