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

利用FIR滤波原理，设计了一个带通型的FIR滤波器，用于实现语音去噪。-According to the principles of FIR filtering,a type of bandpass FIR filter has been designed to achieve the goal of speech enhancement

对语音信号处理时加入噪声，并创建butterworth模拟滤波器。-Noise added speech signal processing, and create butterworth analog filter.
