In the past many speech enhancement methods has been developed. These methods
improved the signal quality but these techniques enhanced the signal quality but were …

This paper presents a comparative evaluation of various mother wavelets for reduction of
mixed highly non-stationary noises to increase the quality and intelligibility in single channel …

This paper presents a comparative analysis for enhancement of noisy single channel Hindi
speech patterns', using a binary mask threshold function in mother wavelet transforms. In …

Speech enhancement is very important step for improving quality and intelligibility of noisy
speech signal. In practical environment more than one noise sources are present, hence it is …

Speech signal analysis is one of the most important fields of study in multi-media
applications. Using automated channels, it is possible to successfully eliminate the …

This paper presents about Adaptive Filter Algorithms used in Embedded Signal Processing
for Speech Enhancement. Filters are generally used to select or to remove or to separate out …

Speech has been embedded into many applications like speech recognition, development
of hearing aid, VoIP, mobile and other forms of personal communication. Speech …

In this paper, a wavelet packet based speech enhancement system is proposed for noise
reduction. In the proposed method, a modulation channel selection is used as a …

Signal denoising for non-stationary digital signals can be effectively succeeded by using
discrete wavelet transform. Selecting of a suitable thresholding method is important to …
