This paper describes a DSP system which based on multi-band excitation voice compression coding algorithm - multi-rate vocoder.
论文设计了一个基于多带激励语音压缩编码算法的DSP系统-多速率声码器。
According to the characteristic of discontinuous voice signal, this compression algorithm provides the function of voice active detection and improves the compress ratio of voice signal.
同时，根据语音信号不连续的特点，压缩算法具有静音识别功能，进一步提高了语音信号的压缩率。
