  • FIR
    绘制一段语音信号的波形并观察其频谱,用三角窗设计一个满足给定相应技术指标的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。

    基于倒谱短时部分反映了语音的声道特性,先用汉明窗取一帧语音,然后经变换得到语音倒谱,将倒谱短时部分取出,进行正交反变换后将得到声道的对数谱,即得到语音频谱的包络。将频谱包络和频谱画在一张图上,有很好的对比效果。获取的包络效果十分好。(Based Cepstral partly reflects the short channel characteristics of the speech, first take a Hamming window with a frame of speech, and speech cepstrum obtained by converting the cepstrum short segment out inverse orthogonal transform to obtain channel will of the spectrum, i.e. to obtain the envelope of the speech spectrum. The spectral envelope and spectral painted on a chart, there is a good contrast. Get the envelope effect is very good.)

    本次课程设计主要介绍了语音信号的录制、语音信号的采集与分析、语音信号的采样、语音信号的频谱分析、加噪后的频谱分析、滤波器的设计以及对于语音信号的回放等知识。通过 Cool Edit录制一段语音信号,运用MATLAB对其进行时域与频域分析,然后设计滤波器加入噪声进行滤波处理,比较滤波前后始于波形或频谱的变化,最后实现对于语音的回放设计。(Digital voice processing filter design)
