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)

Defining the plot Function for the DocPolynom Class The MATLAB plot function creates line graphs. The overloaded plot function selects the domain of the independent variable to be slightly larger than an interval containing all real roots. Then the polyval method is used to evaluate the polynomial at a few hundred points in the domain:
