根据短时傅里叶变换原理，计算并显示该语音段的短时幅度谱和功率谱；根据语谱图显示原理，编程实现该语音段语谱图的计算和显示，并尽量多地分析出语谱图包含的语音特征信息,用MATLAB提供的倒谱计算函数，显示该语音段的复倒谱和倒谱(According to the principle of short-term Fourier transform, the short range spectrum and power spectrum of the speech segment are calculated and displayed. According to the principle of spectrogram display language, programming implementation period of the speech spectrum diagram calculation and display, and as often as possible language phonetic characteristics of spectra contain information provided by the MATLAB cepstrum calculation function, according to the voice of the complex cepstrum and cepstrum)
