The concept of differential linear prediction is presented. It is shown that for voiced speech, differential linear prediction results in a theoretical coding reduction of over twelve bits per frame compared to standard linear prediction. Intelligibility test scores for a 1200 bit per second differential linear predictive coder demonstrate the potential for this technique even in channel error rates up to five percent.
