In this paper, we present a detailed analysis for two generic single-channel Wiener filtering concepts for binaural hearing aids, namely, a dual-channel filter approach (individual filters for individual channels) and a single filter approach (one filter applied to both channels). After a general description of the concept, this scheme is thoroughly(More)
We propose a novel approach for estimating a reverberation model for a robust recognizer according to [1], which is designed to allow distant-talking automatic speech recognition (ASR) in reverberant environments. Based on a few calibration utterances with known transcriptions recorded in the target environment, a maximum likelihood estimator is used to(More)
In this paper, minimization of the statistical dependence is exploited for acoustic source localization purposes. Originally developed for the separation of signal mixtures, we show that Independent Component Analysis (ICA) can also be successfully applied to localize multiple simultaneously active sound sources, with possibly less sensors than sources.(More)
