his MATLAB exercises illustrates an algorithm for estimating the locations of the formants of voiced speech intervals based on the locations of the speech polynomial roots as obtained a frame-based analysis of a speech signal using the method of Linear Prediction Analysis. A key aspect f this algorithm is finding regions of quasi-contiguous speech frames (where the first three formants form a contiguous region over the duration of the voiced region), and then extending these regions (both backward and forward) based on a somewhat weaker criterion for contiguous behavior of the formants. The file 4.7 Formant Estimation.pdf provides a User s Guide for this exercise.
