A GUI for Speech Analysis using LPC

View License

This GUI is used to analyze the speech signal at the selected region of 256 samples. All the calculation is based on the sampling of 8 KHz. First 3 formants of the selected block of samples are derived from the LPC-8 coefficients.

The location of the ROI could be either pointer one or two.

This demo uses the "dualcursor" developed by Scott Hirsch for the interactive signal selection. Only p-file for the "dualcursor" is provided here and the source code could be downloaded from the MATLAB central.
