对一个元音和一个清辅音进行线性预测分析。LPC系数要分别有5阶，15阶和50阶三种情况，在同一坐标图里用不同颜色分别给出对应的LPC包络谱和FFT频谱，并试着对比分析。-A linear prediction of a vowel and a clear consonant. LPC coefficients should be 5 order, 15 and 50 order three cases, in the same coordinate map with different colors were given the corresponding LPC envelope spectrum and FFT spectrum, and try to compare the analysis.
