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. LPC both the speech signal power spectrum estimate, which, LPC coefficients, respectively, five bands, 10 bands, 15 bands and 20 the first four cases, and draw a graph of the FFT power of the signal itself spectrum and four different orders of LPC spectral estimation map, for comparison. LPC and LPCC only examine the autocorrelation method. 3, the number of area ratio method to calculate the variable cross-section of the two pronunciation sound tube simulation graphics, 10 bands can be)
