چکیده
The corruption of speech due to presence of additive background noise causes severe difficulties in various communication environments. This paper presents a novel noise reduction technique based upon a combination of cascaded spectral subtraction and Wiener filter methods in wavelet domain. The scheme’s performance is illustrated by experiments in a noisy car environment, in comparison with spectral subtraction and Wiener filter.

Theoretical Analysis of Musical Noise in Wiener Filter via Higher-Order Statistics
In this paper, we provide a new theoretical analysis of the amount of musical noise generated via Wiener filter based on higher-order statistics. Spectral subtraction and Wiener filter are the most commonly used noise reduction methods, and in our previous study a musical noise assessment theory limited to the spectral subtraction was proposed. Therefore, in this paper, we propose a new theoret...

متن کاملSpectral Subtraction in the Wavelet Domain for Speech Enhancement
In this paper we propose a new approach for speech enhancement. The method used to remove the noise components is a combination of two methods: Wavelet de-noising and spectral subtraction. The idea is to apply the spectral subtraction to wavelet approximations and details coefficients. A new parameter for spectral subtraction in unvoiced speech frames is introduced and the existing power factor...
متن کاملSpeech Enhancement in Presence of Noise using Spectral Subtraction and Wiener Filter
The process of suppressing the back ground noise in speech signals can be improved by subtraction of an estimate of the average noise spectrum from the noisy signal spectrum. The main objective of this paper is to implement and evaluate speech enhancement techniques based on spectral subtraction methods in presence of noise. The two techniques discussed in this paper are spectral subtraction fi...
متن کاملA Computationally Restrained and Single-channel Blind Dereverberation Method Utilizing Iterative Spectral Modifications
A computationally restrained, single-channel, blind dereverberation method is proposed. The proposed method consists of two iterative spectral modifications, which employs spectral subtraction for noise reduction, and a complementary Wiener filter for dereverberation. Modulation transfer function is employed to calculate the dereverberation parameters. Late reverberation is estimated without an...
