Abstract :
In this paper, a completely new waveform speech coding method with named as the half-wave speech entropy coding is presented. Two different approaches are proposed to generate the voiced and the unvoiced codebooks respectively. In addition, the theory of coding and decoding is shown. The result of the experiment shows that the coding method is an effective waveform coding with the benefits of low complexity, high compression rate, low bit rate and good speech quality. These benefits make the new method a competitive candidate for speech coding.
