A method of communicating speech comprising time-warping a residual low b and speech signal to an expanded or compressed version of the residual low b and speech signal, time-warping a high band speech signal to an expanded or compressed version of the high band speech signal, and merging the time-warp ed low band and high band speech signals to give an entire time-warped speec h signal. In the low band, the residual low band speech signal is synthesize d after time-warping of the residual low band signal while in the high band, an unwarped high band signal is synthesized before time-warping of the high band speech signal. The method may further comprise classifying speech segm ents and encoding the speech segments. The encoding of the speech segments m ay be one of code-excited linear prediction, noise-excited linear prediction or 1/8 frame (silence) coding.
