<br/>   abstract  = {Over the last years several algorithms for the dereverberation of speech
signals based on the discrete model of speech production have been proposed. They
have in common that they rely on a model consisting of an excitation source and
a time-varying vocal tract filter. In this paper we investigate the application of the
postfilter algorithm used in Code Excited Linear Prediction (CELP) speech coding
for the purpose of speech dereverberation. We show that in case of a reverberant
signal, the amplitudes of the unwanted peaks in the excitation signal are attenuated
and that this approach is capable of reducing early reverberation. Furthermore, we
compare the new approach with state-of-the-art speech source-model dereverberation
algorithms and evaluate the proposed method in a single-channel approach.},
