并口调试软件，可更改并口地址，可以手动输入，但必须加上0X，否则认为是错误地址-Parallel debugging software, change the parallel port address, you can manually input, but it must be coupled with 0X, otherwise considered to be the wrong address

MFCC已经广泛地应用在语音识别领域。由于Mel频率与Hz频率之间非线性的对应关系，使得MFCC随着频率的提高，其计算精度随之下降。因此，在应用中常常只使用低频MFCC，而丢弃中高频MFCC。这个程序是求MFCC 的-MFCC has been widely used in speech recognition. Mel frequency Hz as a nonlinear correspondence relationship between the frequency, such as t
