Moving Toward High Precision Dynamical Modelling in Hidden Markov Models
Sébastien Gagnon, Jean Rouat
Hidden Markov Model (HMM) is often regarded as the dynamical model of choice in many fields and applications. It is also at the heart of most state-of-the-art speech recognition sy…
Robust 3D Localization and Tracking of Sound Sources Using Beamforming and Particle Filtering
Jean-Marc Valin, François Michaud, Jean Rouat
In this paper we present a new robust sound source localization and tracking method using an array of eight microphones (US patent pending) . The method uses a steered beamformer b…
Microphone array post-filter for separation of simultaneous non-stationary sources
Jean-Marc Valin, Jean Rouat, François Michaud
Microphone array post-filters have demonstrated their ability to greatly reduce noise at the output of a beamformer. However, current techniques only consider a single source of in…
Enhanced Robot Audition Based on Microphone Array Source Separation with Post-Filter
Jean-Marc Valin, Jean Rouat, François Michaud
We propose a system that gives a mobile robot the ability to separate simultaneous sound sources. A microphone array is used along with a real-time dedicated implementation of Geom…
Localization of Simultaneous Moving Sound Sources for Mobile Robot Using a Frequency-Domain Steered Beamformer Approach
Jean-Marc Valin, François Michaud, Brahim Hadjou +1
Mobile robots in real-life settings would benefit from being able to localize sound sources. Such a capability can nicely complement vision to help localize a person or an interest…
Robust Sound Source Localization Using a Microphone Array on a Mobile Robot
Jean-Marc Valin, François Michaud, Jean Rouat +1
The hearing sense on a mobile robot is important because it is omnidirectional and it does not require direct line-of-sight with the sound source. Such capabilities can nicely comp…
