This paper elaborates the methods of making clear and voiced codebooks in detail, and gives the process of codec implementation. Experimental results show that the speech waveform coding method has the characteristics of low complexity and high compression ratio, and the reconstructed speech quality is close to the G.72 9 coding level. The characteristics of this coding method: Noisy speech coding can get good quality; Strong confidentiality, suitable for secure communication; Has good algorithm scalability. Therefore, this method is a new speech waveform coding method with broad application prospects
