Main area of research
Speech enhancement

Tobias Wolff studied Electrical Engineering and Communications at Technische Universität Darmstadt (TUD), Germany. He received the Dipl.-Ing. degree in 2006 and the Dr.-Ing. degree in 2010 both from the Signal Processing Group at TUD. From May 2005 to December 2005 and from June 2007 to September 2007 he was a visiting researcher at the Image Processing Laboratory at University of California Santa Barbara (USCB). Since April 2009 he is a senior research engineer in the acoustic Speech Enhancement Department at Nuance Communications Deutschland GmbH. His main interests are algorithms for multichannel speech enhancement in noisy and reverberant environments. Tobias contributes as a supervisor in the Maire Curie International Training Network "DREAMS" to improve speech recognition performance in the presence of room reverberation.

A subband based acoustic source localization system for reverberant environments

In this paper an efficient acoustic source localization sys­tem is described which works within a subband process­ing framework and is robust against reverberation. The proposed

Spatial maximum a posteriori post-filtering for arbitrary beamforming

We present a new approach for residual transient noise suppression at the output of an arbitrary beamformer. A spatial optimum esti­mate for the instantaneous a

A compact microphone array system with spatial post-filtering for automotive applications

Compact microphone arrays allow for directional filtering with a minimum of installation space. They are therefore particularly suitable for automotive applications. Typically, compact arrays are
