This MATLAB exercise computes and plots the roots of either an LPC polynomial or the resulting set of LSP polynomials, for all frames of a specified speech file, and superimposes the resulting root plots over either a conventional wideband spectrogram of the speech, or an LPC spectrogram of the speech. For plotting the roots of the LPC polynomial, a threshold is used in order to limit the roots being plotted to those whose magnitude exceeds a specified threshold (e.g., 0.85 or 0.9). The file '3.21 Plot Roots.pdf' provides a User's Guide for this exercise.
