Degradation of speech signal due to adverse conditions is the major challenge for automatic speech recognition (ASR) systems. This paper introduces a novel approach to estimate an Ideal Neighbourhood Mask (INM) for speech segregation based on deep ne

In this paper, we present a wavelet coefficients masking based on Local Binary Patterns (WLBP) approach to enhance the temporal spectra of the wavelet coefficients for speech enhancement. This technique exploits the wavelet denoising scheme, which sp

A novel approach for speech enhancement applications by applying spectral mask estimation is introduced. The new application uses the local binary patterns to estimate an ideal neighbourhood mask. This will indicate which time–frequency units of th

The nonlinear distortion in the cepstral coefficients domain introduced by additive noise in the speech signal, results in high degradation performance in systems of Automatic Speech Recognition (ASR). For this reason, we propose a median filter whic
