CA 2144823

A method of encoding speech by analyzing a digitized speech signal to determine excitation parameters for the digitized speech signal is disclosed. The method includes dividing the digitized speech signal into at least two frequency bands, performing a nonlinear operation on at least one of the frequency bands to produce a modified frequency band, and determining whether the modified frequency band is voiced or unvoiced. The method is useful in encoding speech.
