Following magnetic transcranial stimulation (TCS) a post-excitatory pause can be observed in surface electromyographic (EMG) recordings from pre-innervated muscles. We studied the duration of this silent period (SP) in the abductor pollicis brevis muscle while varying the stimulus intensity (SI) and the amount of the voluntary tonic contraction in 23 normal(More)
—Successful localization of sound sources in rever-berant enclosures is an important prerequisite for many spatial signal processing algorithms. We investigate the use of a weighted fuzzy c-means cluster algorithm for robust source localization using location cues extracted from a microphone array. In order to increase the algorithm's robustness against(More)
This paper investigates the use of DUET, a recently proposed blind source separation method, as front-end for missing data speech recognition. Based on the attenuation and delay estimation in stereo signals soft time-frequency masks are designed to extract a target speaker from a mixture containing multiple speech sources. A postprocessing step is(More)
This paper presents a novel approach to combine microphone array processing and robust speech recognition for reverberant multi-speaker environments. Spatial cues are extracted from a microphone array and automatically clustered to estimate local-ization masks in the time-frequency domain. The localization masks are then used to blindly design adaptive(More)
