多带激励语音压缩算法的仿真实现

The Simulation of a Multiband Excitation Speech Compression Algorithm

作者从语音信号的多带激励（ＭＢＥ）模型出发，对ＭＢＥ语音压缩算法的原理作了详细的阐述，指出了它相对于传统ＬＰＣ等算法的优越性，并在计算机上进行了仿真实现，给出了实验结果。作者最后就合成语音的质量、算法复杂度等方面，对ＭＢＥ声码器和部分常用标准语音压缩编码方案作了比较。

This paper describes from MBE model of speech signals by proceeding the principle of multiband excitation(MBE) speech compression algorithm,to show its advantages over others, such as LPC algorithm. The simulation of this algorithm and its results are also presented. At the end of this article, we contrast MBE vocoder with some standard speech coding programmes, in the cases of the synthesized speech quality , computing complexity, etc., and then point oout the direction of further research.
