摘要：

The paper described a 12.8kbit/s LD-CELP speech coding algorithm on the basis of G.728 speech codec, and presented the concept of Codeword Use Frequency (CUF). The experiment results show that the method can decrease effectively the complexity of vector quantization codebook and hold better synthesis speech duality than other same type ways. The algorithm is implemented in duplex real-time on high-speed DSP system with two chip TMS320C31s.
