lpc
1.用matlab实现对一个元音和一个清辅音的LPC系数,LPCC系数和MFCC系数的提取。
2,用LPC对这两个语音信号的功率谱进行估计,其中,LPC系数要分别有5阶,10阶,15阶和20阶四种情况,并在一个图里画出信号本身的FFT功率谱和四条不同阶数的LPC谱估计图,以作比较。注意,LPC和LPCC只考察自相关法。
3,用对数面积比的方法来求出这两个发音的变截面声管模拟图形,10阶即可(Using matlab to achieve the LPC coefficients of a vowel and a voiceless consonant, the extraction of LPCC Features coefficients and MFCC coefficients.
