Abstract

Empirical Mode Decomposition (EMD) [1], a multi-resolution method for reducing speech signal noise, is presented. The suggested technique for speech de-noising is entirely data-driven. Sifting is a temporal decomposition process that adaptively breaks down a noisy signal into oscillatory components known as Intrinsic Mode Functions (IMFs). The method's fundamental idea is to use a shrinkage function to threshold IMFs before reconstructing the signal. Speech with varying noise levels is subjected to the de-noising technique, and the outcomes are contrasted with wavelet compression. The research is limited to signals with white Gaussian noise additively present distorted in them. Afterwards, pitch is extracted from the de-noised signal using spectral pitch analysis.
