1 录入一段语音，对其进行时域频域处理，通过变频、变速达到变声目的，且使处理后的语音信号不影响正常收听与理解。 2 用图形用户界面（GUI）对上述变声前变声后进行时域频域图形输出，不同的频率、速度有不同的输出，且对前后波形进行比较 (1 entry a voice, the frequency domain and time domain by frequency conversion variable speed, processing to make the treatment and voice purpose, after the speech signal shall not affect the normal to listen to and understand. 2 with the graphical user interface (GUI) voice of the above voice before after the frequency domain in the time domain graphics output, different frequency, speed have different output, and compared before and after waveform )

说明：  matlab实现的DS证据理论代码简单实现，加了一些注释，适用于独立的单一命题。(function for D-S)

根据公式I（n-1）=（1-In）/n 令I11=0计算I1 到I10； 根据公式In=1-nI(n-1) 令I0=0.6321 计算I1到I7； 根据公式X2=a ， 令a=2，计算X的值。(According to the formula I(n-1)=(1-In)/n ，set I11 equals zero，and count I1 to I10. According to the formula In=1-nI(n-1)，set I11 equals zero，and count I1 to I10. According to the formula X square equals a ，set a equals two ，then calculate X )
