Autocorrelation_Pit​ch_Detector

Estimate the pitch period of a speech file using a short-time autocorrelation analysis methods.

This speech processing exercise uses the methods of short-time signal processing analysis to estimate the pitch period of a user specified speech signal. This particular pitch period detector uses 4 variants of the short-time autocorrelation method, namely standard autocorrelation, modified autocorrelation, center-clipped autocorrelation, and 3-level autocorrelation, to provide statistically robust estimates of pitch period. The file '4.3 Autocorrelation Pitch Detector.pdf' provides a User's Guide for this exercise.
