Pitch Modification on Speech Signals using PSOLA Algorithm
This project implemented in June 2020 for Speech Processing course in Bogazici University.
Simple pitch modification program that implements Pitch-Synchronous Overlap Add Algorithm on top of YIN pitch detection algorithm.
The program segments the speech using pitch information from the pitch detector and allows user to change each segment's pitch independently.
Simple Console based GUI was implemented for the ease of use. Two speech samples are also provided for testing.
Python 3.6
Required libraries: numpy, librosa, scipy, matplotlib
