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） -Wiener filter-based de-noising of the voice call Matlab source code the way: output = WienerScalart96 (signal, fs, IS) signal- voice input with noise fs---- voice signal sampling rate IS---- Start mute end used to estimate the noise variance (units of seconds to do, the default is 0.25 seconds) Platform: |

Description: The purpose of this project is to create a different system for processing voice signals and from which we draw useful conclusions about these brands.
More specifically, the system will first filter the voice signal with a pass bandwidth (chebyshev probably type 2) to reduce the presence of noise in it and then we can calculate:
• what limits the signal word out (segmentation)
• how are these words
• the characteristic frequency of the voice of the speaker of each file (voice pitch). -The purpose of this project is to create a different system for processing voice signals and from which we draw useful conclusions about these brands.
