WASPAA papers on source localisation & source separation

I am delighted that three of our papers were accepted for WASPAA 2021! Aidan Hogg's work [1] proposes to combine spectral features (voice pitch) and spatial features (source direction-of-arrival) in order to track multiple, competing speakers in complex scenarios. Vincent Neo's work [2] proposes to exploit spatial, temporal - and hence spectral...

“Optimized Self-Localization for SLAM in Dynamic Scenes using Probability Hypothesis Density Filters”

Open Access: IEEE Transactions on Signal Processing Authors:  Christine Evers and Patrick A. Naylor Abstract:  In many applications, sensors that map the positions of objects in unknown environments are installed on dynamic platforms. As measurements are relative to the observer's sensors, scene mapping requires accurate knowledge of the observer state. However, in practice, observer reports...

“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...
