A New Method Based on Spectral Subtraction for Speech Dereverberation
A new monaural method for the suppression of late room reverberation from speech signals, based on spectral subtraction, is presented. The problem of reverberation suppression differs from classical speech de-noising in that the “reverberation noise” is non stationary. In this paper, the use of a novel estimator of the non-stationary reverberationnoise power spectrum, based on a statistical mod...
متن کاملJoint Estimation of Reverberation Time and Direct-to-Reverberation Ratio from Speech using Auditory-Inspired Features
Blind estimation of acoustic room parameters such as the reverberation time T60 and the direct-to-reverberation ratio (DRR) is still a challenging task, especially in case of blind estimation from reverberant speech signals. In this work, a novel approach is proposed for joint estimation of T60 and DRR from wideband speech in noisy conditions. 2D Gabor filters arranged in a filterbank are explo...
متن کاملSpectral Subtraction and Spectral Estimation
The problem of spectral subtraction, to estimate the parameters of a single source in colored noise, is used to show the relationships between the likelihood formulation and spectral density estimation. Reported previously as a filter bank processing for spectral estimation, it is shown that the normalized Capon estimate is the natural tool for source location in 1-d and 2-d scenarios when the ...
متن کاملSingle–Channel Speech Dereverberation based on Spectral Subtraction
Speech signals recorded with a distant microphone usually contain reverberation, which degrades the fidelity and intelligibility of speech in devices such as ’hands–free’ conference telephones, automatic speech recognition and hearing aids. One important effect of reverberation on speech is overlap–masking, i.e. the energy of the previous phonemes is smeared over time, and overlaps following ph...
متن کاملBlind Reverberation Time Estimation
This paper presents a method, which is able to give a blind estimation of the reverberation time of an enclosed space, using only the signal from two or more spatially distributed receivers, for example a binaural signal. There is no need for a controlled or known excitation signal, and there are no special requirements for the excitation signal. The method works with any kind of acoustic sourc...
