lpc varying L
This MATLAB exercise illustrates the matching behavior of the LPC polynomial log magnitude spectrum to the log magnitude spectrum of the STFT of the designated input frame of speech as a function of the frame size, Lm for a range of values of Lm; (e.g., Lm =Linit, Linit+Ldelta, ... , Linit+4*Ldelta) msec. This exercise processes a frame of a speech file (from a designated starting sample and a varying frame duration), and plots the LPC polynomial log magnitude spectrum as a function of the speech frame duration, Lm, for each of 5 frame durations, and compares the results with the log magnitude spectrum of the STFT of the designated frame of speech.
