Abstract
This disclosure provides a method of correcting errors in a digital speech signal, a speech decoder, a handset or mobile radio, and a base station or console. The method includes receiving a voice bit stream including voicing bits of a current frame, voicing bits of a prior frame, and a voicing confidence measure for the current frame; generating a set of common voicing patterns for the current frame; resampling voicing bands of the prior frame, so that the number of voicing bands in the resampled prior frame is the same as the number of voicing bands in the current frame; determining a distance for each of the set of common voicing patterns with respect to the current frame and the prior frame; and replacing the current frame with a particular voicing pattern in the set of common voicing patterns, wherein the particular voicing pattern has the minimum distance.
