假设一段语音信号，用其作为序列，编程实现LBG算法产生码书。(Assuming a speech signal, use it as a sequence, programming the LBG algorithm to generate the codebook.)

这是G.723和G.729的音频编解码的源代码，当在网络带宽不够的时候可考虑采用该语音编码方式。(This is the G.723 and G.729 audio codec source code, When the network bandwidth may be insufficient time to consider the use of the voice coding.)

可以对处理后的语音进行一个客观上的评判，提供客观评价因子。(It is possible to make an objective evaluation of the processed speech and provide an objective evaluation factor.)
