A GUI for Speech Analysis using LPC

| Watch this File

File Information

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.

For more information on this example:


Dualcursor inspired this file.
