“Sparse parametric modeling of the early part of acoustic impulse responses”

IEEE Xplore Access: Proc. European Signal Processing Conference (EUSIPCO) Authors:  Constantinos Papayannis, Christine Evers and Patrick A. Naylor Abstract:  Acoustic channels are typically described by their Acoustic Impulse Response (AIR) as a Moving Average (MA) process. Such AIRs are often considered in terms of their early and late parts, describing discrete reflections and the diffuse...

“Discriminative feature domains for reverberant acoustic environments”

IEEE Xplore Access: in Proc. IEEE Intl. Conf. on Acoustics, Speech and Signal Processing (ICASSP) Authors:  C. Papayiannis, C. Evers, and P. A. Naylor Abstract: Several speech processing and audio data-mining applications rely on a description of the acoustic environment as a feature vector for classification. The discriminative properties of the feature domain play a...

“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...
