Analysis of Speech Signal Compression at various levels and wavelets using DWT
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 7
Abstract
As the multimedia technology progresses, so does the need of speech compression for efficient and cheaper transmission. Discrete Wavelet Transform technique aims at providing effective compression in this field. This paper focuses on the analysis of compression ratios for various wavelets at different levels for a speech sample. In our observation, we determined the best results for the symlet2 wavelet type in terms of the compression ratio and overall audio quality. This analysis was performed on MATLAB 7.1 R2009 on an Intel i-5 processor based system.
