In this work, we are interested in developing a speech denoising tool by using a discrete
wavelet packet transform (DWPT). This speech denoising tool will be employed for …

This paper presents an improved speech enhancement technique based on wavelet
transform along with excitation-based classification of speech to eliminate noise from …

A speech enhancement system for noisy speech signals under different environments,
namely airport, babble, car, exhibition, restaurant, station, street and train, is designed and …

The main aim of the speech enhancement is to refine the human perception of system
decoding by processing noisy voice signals. In the speech enhancement process …

This paper investigates the use of wavelet transform for denoising speech signals
contaminated with common noises. Shown are the basic principles of wavelet transform as …

In this paper, Modified Improved Arctan Thresholding and two Hybrid Thresholding schemes
(TH-I and TH-II) have been proposed and successfully used in Wavelet Thresholding the …

In hands free speech communication environments situation occurs that speech is
superposed by background noise. Over the past few decades there is tremendous increase …

This paper introduces a novel speech enhancement system based on a wavelet denoising
framework. In this system, the noisy speech is first preprocessed using a generalized …
