语音信号的G.711编码。 The source code has been modified by simplifying the ADPCM algorithm to increase running speed. Here, the quantizer scale factor, y(k), is determined by "unlocked" factor yu(k) only. The factor yl(k) and speed-contral factor al(k) are ignored.-G.711 speech signal coding. The source code has been modified by simplifying the ADPCM algorithm to increase running speed.

文字阅读器，运行前须安装speechsdk51.exe和speechsdk51LangPack.exe语音引擎，在微软网站上可以下载到。-text reader, prior to the operation and installation speechsdk51.exe speechsdk51LangPack.exe voice engine, the Microsoft Web site to download.

编译时需要intel C++编译器支持,程序主要功能显示语音波形,画出窄带语谱图,以及语音基频变化曲线-need intel compiler C compiler support, principally voice waveform display function, he painted the phrase narrowband spectrum, and the voice-frequency curve

G.729aa 编码器和解码器代码 G.729A 是 G.729 的降低的复杂性标准之一。G.729 是国际电信联盟-T 语音压缩算法，基于共轭结构化代数代码激动的线性预测 (CS-ACELP）。G.729A 压缩 8 kHz 线性音频信号和对他们进行传输在 8 Kbps.输入进行编码为 16 位 PCM。输入码流是分割成 10ms年帧和处理。预测分析做使用合成的筛选器的顺序 10。

g729b_pc.rar是G729语音压缩标准的附件B的C语言实现标准源代码。-g729b_pc.rar is decode voice compression standards Annex B C Language Standard code.
