Description: 基于Wiener滤波的语音消噪Matlab源程序
调用方式：
output=WienerScalart96(signal,fs,IS)
signal－－输入含噪语音
fs－－－－语音信号采样率
IS－－－－起始静音端，用来估计噪声方差（秒做单位，默认是0.25秒）

Description: Wiener filter based on tracking a priori SNR usingDecision-Directed
method, proposed by Scalart et al 96. In this method it is assumed that
SNRpost=SNRprior +1. based on this the Wiener Filter can be adapted to a
model like Ephraims model in which we have a gain function which is a
function of a priori SNR and a priori SNR is being tracked using Decision
Directed method.

Description: 维纳滤波语音增强算法:语音增强算法的维纳滤波器，通过scalart 1996提出的实现。使用一个决策指导的方法跟踪的先验信噪比。请注意，该信号的第一0.25sec用于模型的噪声，即，它是假定的演讲之后，0.25sec开始-Wiener Filter for Noisy Speech Enhancement, implemented as proposed by Scalart 1996. Uses a decision directed method to track the a priori SNR. Note that the first 0.25sec of the signal is used to model the noise, that is, it is assumed that speech starts after that 0.25sec

Description: 维纳滤波器（Wiener filter）是由数学家维纳（Rorbert Wiener）提出的一种以最小平方为最优准则的线性滤波器。在一定的约束条件下，其输出与一给定函数（通常称为期望输出）的差的平方达到最小，通过数学运算最终可变为一个托布利兹方程的求解问题。维纳滤波器又被称为最小二乘滤波器或最小平方滤波器，目前是基本的滤波方法之一。-Wiener filter (Wiener filter) is caused by a mathematician Wiener (Rorbert Wiener) proposed guidelines for the minimum square optimal linear filter. Under certain constraints, which outputs a given function (often called the desired output) reaches the minimum squared differential, the final mathematical operation may become a problem solving Equation Leeds Taub. Wiener filter is also known as the least squares filter or least squares filter, currently one of the basic filtering methods.
