此代码可以对一段语音进行分析并画出语谱图。-This code can be a voice for analysis and draw the spectrogram.

语音增强算法，谱减法、小波变换以及数学形态学等的语音增强算法针对信噪比、语谱图、去噪情况，分析比较-Speech enhancement algorithm, spectral subtraction, wavelet transform and mathematical morphology speech enhancement algorithm for signal-to-noise ratio, the spectrogram denoising situation analysis

matlab编程，画出一段语音的语谱图，在不同时间声音的不同频率，可以比较出有声段和无声段的能量不同。-Matlab programming, draw the spectrogram of a voice, the sound of different frequencies in different time, you can compare audio segment and the energy of the silent segment.

此程序可以用于计算语音信号的语谱图，语谱图对语音识别、语音合成等方面都有着显著的作用和影响。-This program can be used to calculate the speech signal spectrum, the spectrum of speech recognition, speech synthesis and other aspects have a significant role and influence.
