Blind Speech Dereverberation Based on a Statistical Model

2012 IEEE International Conference on Multimedia and Expo, 2012
We present an algorithm to dereverberate single-channel audio signals in both noisy and noise-free acoustical environments. Recently, the model-based dereverberation that use the statistical model for room impulse responses (RIRs) is considered to be a fairly attractive approach for reverberant speech, since existing model-based estimators show the ...

Blind multichannel identification for speech dereverberation and enhancement

2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004
A multichannel wideband signal dereverberation and enhancement method is proposed in this paper. It uses the blindly estimated impulse responses (IR) relating the signal source and each sensor to form a multiple input inverse filter (MINT) for speech dereverberation and enhancement with extended generalized sidelobe canceller (GSC).

Blind dereverberation of a speech signal

Acoustical Physics, 2008
Possibilities to eliminate the reverberation from a speech signal are investigated by applying the method based on the determination of the parameters of the reverberation frequency response from the cepstrum of the reverberation-distorted signal.

Dereverberation of speech signals based on linear prediction

Interspeech 2004, 2004
This paper proposes an algorithm for the blind dereverberation of speech signals based on a two-channel linear prediction. Traditional dereverberation methods usually achieve good performance when the input signal is white noise. However, when dealing with colored signals generated by an autoregressive (AR) process such as speech, the generating AR ...
