SPEECH COMPRESSION ANALYSIS USING MATLAB

Speech Compression Analysis Using Matlab

The growth of the cellular technology and wireless networks all over the world has increased the demand for digital information by manifold. This massive demand poses difficulties for handling huge amounts of data that need to be stored and transferred. To overcome this problem we can compress the information by removing the redundancies present in it. Redundancies are the major source of gener...

JPEG Compression Using MATLAB

Creating, editing, and generating images in a very regular system today is a major priority. The original image data generated by the camera sensor is very large to store, so the efficiency is not high. Mobile or bandwidthlimited systems become particularly cumbersome, where the object is a conservative bandwidth cost, such as the World Wide Web. This situation requires the use of efficient ima...

Speech Compression using Analysis by Synthesis

Linear prediction plays a fundamental role in all aspects of speech. Its use seems natural and obvious since for a speech signal the value of its current sample can be well modeled as a linear combination of its past values. Calculation for predictor coefficients with the help of automatic code generation gives the solution for early and efficient computing. Automatic code generation is a fast ...

Speech Compression using ADPCM

We propose a simple speech compression algorithm using subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm. Although speech data are stored in a semiconductor memory device, its capacity and the available network capacity are limited. Therefore, it is necessary to compress the data as much as possible. The first is that the reconstructed datum must be understood c...
