G.723.1语音编码器的研究

Research of G.723.1 Speech Coder

本文介绍了G.723.1语音编码器的概念,分析了它的技术和特点。我们建议对G.723.1语音编码器的编码时间进行优化。并提出改进一些计算量较大的模块,如基音估计、自适应码本搜索、固定码本搜索等模块。

This paper introduces concept of G.723.1 speech coder and analyses its technology and feature. We advise to optimize its running time of G.723.1 speech coder. We put forward to improve some modules with large computational complexity, such as pitch estimation module, the adaptive and the fixed code-book research modules.
