Welcome to Speech Signal Processing Lab!
Introduction

The objective of this lab is to provide hands on experience in processing speech signals for extraction of information for various applications. Students will learn to process their own speech and listen to the processed speech to get a feel for effects of various signal processing operations on speech signals.
