“Source tracking using moving microphone arrays for robot audition”

IEEE Xplore Access: Proc. IEEE Intl. Conf. on Acoustics, Speech and Signal Processing (ICASSP) Authors: C. Evers, Y. Dorfan, S. Gannot, and P. A. Naylor Abstract: Intuitive spoken dialogues are a prerequisite for human-robot interaction. In many practical situations, robots must be able to identify and focus on sources of interest in the presence of...

“Audio-visual tracking by density approximation in a sequential Bayesian filtering framework”

IEEE Xplore Access: Proc. Joint Workshop on Hands-Free Speech Communications and Microphone Arrays (HSCMA) Authors: Israel D. Gebru, Christine Evers, Patrick A. Naylor, Radu Horaud Abstract: This paper proposes a novel audio-visual tracking approach that exploits constructively audio and visual modalities in order to estimate trajectories of multiple people in a joint state space. The...

“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...

“2D direction of arrival estimation of multiple moving sources using a spherical microphone array”

IEEEXplore Access: in Proc. European Signal Processing Conf. (EUSIPCO), Budapest, Hungary, Aug. 2016 Authors: A. H. Moore, C. Evers , and P. A. Naylor, Abstract: Direction of arrival estimation using a spherical microphone array is an important and growing research area. One promising algorithm is the recently proposed Subspace Pseudo-Intensity Vector method. In this contribution...

“Direction of Arrival Estimation in the Spherical Harmonic Domain Using Subspace Pseudointensity Vectors”

IEEE Xplore: IEEE/ACM Transactions on Audio, Speech, and Language Processing Authors: Alastair H. Moore, Christine Evers, and Patrick A. Naylor Abstract: Direction of arrival (DOA) estimation is a fundamental problem in acoustic signal processing. It is used in a diverse range of applications, including spatial filtering, speech dereverberation, source separation and diarization. Intensity vector-based DOA...

“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...
