File Information

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.

Required Products MATLAB
MATLAB release MATLAB 8.0 (R2012b)

Other requirements Requires speech files and functions folder.
