中文说明：这MATLAB行使LPC多项式匹配的性能进行比较，以演讲的框架，与LSP来自LPC多项式得到的（线谱对）的多项式，并绘制相关联的各种信号语音帧的LPC和LSP表示。这个MATLAB程序处理语音的窗加权帧（从指定话音文件，与指定起始样品，并与指定的帧持续时间）。行使计算的LPC多项式匹配的语音帧，然后从LPC多项式到该对的LSP的多项式（P和Q）的转换，并绘制结果。
English Description：
This MATLAB exercise compares the properties of the LPC polynomial match to a frame of speech, with the LSP(Line Spectral Pair) polynomials obtained from the LPC polynomial, and plots the various signals associated withLPC and LSP representations of the frame of speech. This MATLAB program processes a window-weighted frame of speech (from a designated speech file, with designated starting sample and with a designated frame duration). The exercise computes the LPC polynomial match to the speech frame, and then converts from the LPC polynomial to the pair of LSP polynomials (P and Q), and plots the results.
