| 摘 要： | 将自适应码本搜索和代数码本搜索相级联的方法运用到低延迟码激励线性预测算法的矢量量化模块中,将传统的5维码本结构的LD-CELP的码率降为10k/s。通过PC仿真测试,其合成语音质量接近16kb/s的G.728。

| Abstract: | The cascade connection of the selfadaptive codebook search and algebra codebook search was applied into the Vector quantization module of low-delay code incentive linear prediction algorithm,and LD-CELP code rate of traditional 5D codebook structure was reduced to 0 k/s.And through PC simulation test,the quality of synthesized speech was close to 16 kb/sof G.728. |
