“Speaker tracking in reverberant environments using multiple directions of arrival”

IEEE Xplore Access: in Proc. Hands-free Speech Communications and Microphone Arrays (HSCMA) Authors: Christine Evers, Boaz Rafaely, and Patrick A. Naylor Abstract: Accurate estimation of the Direction of Arrival (DOA) of a sound source is an important prerequisite for a wide range of acoustic signal processing applications. However, in enclosed environments, early reflections and late...

“Speaker localization with moving microphone arrays”

IEEEXplore Access: in Proc. European Signal Processing Conf. (EUSIPCO), Budapest, Hungary, Aug. 2016 Authors: C. Evers , Y. Dorfan, S. Gannot, and P. A. Naylor Abstract: Speaker localization algorithms often assume static location for all sensors. This assumption simplifies the models used, since all acoustic transfer functions are linear time invariant. In many applications this...

“Direction of arrival estimation using pseudo-intensity vectors with direct-path dominance test”

IEEEXplore Access: in Proc. European Signal Processing Conference (EUSIPCO), Nice, August 2015 Authors: A. H. Moore, C. Evers , and P. A. Naylor Abstract: The accuracy of direction of arrival estimation tends to degrade under reverberant conditions due to the presence of reflected signal components which are correlated with the direct path. The recently proposed...
