五岳鑫语音盒驱动程序，带完整例程，可以对来电自动识别，来电弹屏，自动检测外线用户打进时的振铃信号和内线用户摘挂机动作； ★ 可控制外线的摘挂机，内线的馈电或振铃； ★ 将数字化电脑语音文件放送到电话线上； ★ 将电话语音录制成数字化电脑语音文件； ★ 接收用户的电话机按键信号(双音多频码)； ★ 检测电话线路返回的各种信号音状态，如：拨号音、忙音、回铃音等； ★ 电话卡上任意两通道可连接相互通话。当卡上同时配有内外线时，内外线间也可连接通话。该卡可实现程控机的所有功能 -err

语音频率分析使用matlab实现，很经典了-Voice frequency analysis using matlab implementation, it is the classic of the Hehe

:高斯混合模型(GMM)是一种经典的说话人识别算法，本文在实现其算法的同时，主要模拟了不同噪声环境情况下高斯混合模型 (GMM)的杭嗓声性能，得到了一些有益结论。 -Gaussian mixture model (GMM) is a classic speaker recognition algorithms, this algorithm at the same time in fulfilling its main simulated environmental conditions under different noise Gaussian mixture model (GMM) of the Hang throat sound performance, and obtained some useful conclusions.

本文分析了用经验模态分解( Empirical Mode Decomposition ,EMD) 方法处理非平稳噪声信号的基本原理 , 并利用 EMD 方法有效地消除了高斯白噪声对瞬态散射回波的干扰. 文中以一人工合成瞬态回波为例 ,对本方法的有 效性作了检验.-This paper analyzes the use of empirical mode decomposition (Empirical Mode Decomposition, EMD) method to deal with non-stationary noise signals in the basic principles and methods of use of EMD effectively eliminates the Gaussian white noise on the transient scattering echo interference. Text in one artificial Synthesis of transient echoes as an example of the effectiveness of this method were tested.

高质量的语音处理工具箱，包括分帧，预处理，求基频等-high-quality voice processing toolkit, including the frame, pretreatment, such as for frequency

2400 bps MELP语音编解码器 定点运算算法-2400 bps MELP speech codec algorithm sentinel Operational

简单的基于门限值的语音端点检测。先将数字化的语音信号封装成帧，利用最大的帧幅值乘以一个比例因子得到门限值-Simple threshold-based voice end point detection. First，framing the digital voice signal , then using the maximum amplitude to multiply a frame scale factor to get threshold

很多人不会在windows里编译htk,因此所有htk3.2.1的程序在windows里编译了一次,可以在命令窗口下直接使用这些指令.-many people will not compile the windows Lane HTK, all the procedures htk3.2.1 windows Lane compiler, the one window in order to use them under direct orders.

语音识别源代码，可以对固定的某些语音实行识别，对于开发语音识别的朋友，具有很好的参考用途-Speech recognition source code, can be fixed to implement some voice recognition, speech recognition for the development of friends, an excellent reference
