[Voice Compress] yuyinxinhaolupoquzao DL : 1: 本课程设计的主要目的是在MATLAB环境下，使用窗口设计法设计一个滤波器，并对语音信号进行滤波去噪。开发平台为MATLAB7.0，设计方法为窗口设计法。用麦克风采集一段语音信号，绘制波形并观察其频谱，给定相应技术指标，用凯塞窗设计一个满足指标的FIR滤波器，对该语音信号进行滤波去噪处理，比较滤波前后的波形和频谱并进行分析。在滤波前后语音信号波形的变化中，由于我们录制的语音信号噪声不大，所以观察并不明显，但在频域波形中，我们可以明显的看到设计的滤波器对语音信号进行了滤波处理，将噪声进行了滤除。此次滤波基本达到了要求，完成了设计指标。-The main purpose of this course is designed in the MATLAB environment, the use of window design method to design a filter, and the voice signal filtering noise. Development platform for MATLAB7.0, design methods for the window design method. Collecting a voice signal with a microphone, and observe its spectrum waveform drawing, given the corresponding technical indicators, using a Kaiser window design FIR filter meet the target, the filter denoising speech signal processing, a waveform and spectrum before and after filtering and analyzed. Before and after the filter in the speech signal waveform changes, because we recorded voice signal to noise is low, they observed not obvious, but the waveform in the frequency domain, we can clearly see the design of a filter for the filtering of the speech signal processing , the noise were filtered out. The filtering basically reached the requirements to complete the design specifications.
