Speech Compression Using Linear Predictive Coding

The aim of the project is to develop a system for encoding good quality speech at a low bit rate. To implement this we have used most powerful speech analysis technique called Linear Predictive Coding (LPC). It uses 10 order Levinson-Durbin Recursion algorithm to accomplish the task. It provides extremely accurate estimates of speech parameters, and is relatively efficient for computation.The s...

Sparsity in Linear Predictive Coding of Speech

This thesis deals with developing improved techniques for speech coding based on the recent developments in sparse signal representation. In particular, this work is motivated by the need to address some of the limitations of the wellknown linear prediction (LP) model currently applied in many modern speech coders. In the first part of the thesis, we provide an overview of Sparse Linear Predict...

Speech Compression Using Linear Predictive Coding(lpc)

One of the most powerful speech analysis techniques is the method of linear predictive analysis. This method has become the predominant technique for representing speech for low bit rate transmission or storage. The importance of this method lies both in its ability to provide extremely accurate estimates of the speech parameters and in its relative speed of computation. The basic idea behind l...
