Emergency incidents detection in assisted living environments utilizing sound and visual perceptual components
(2009)The paper presents the concept and an initial implementation of a patient status awareness system that may be used for patient activity interpretation and emergency recognition in cases like elder falls. The system utilizes ... -
Experiments on far-field multichannel speech processing in smart homes
(2013)In this paper, we examine three problems that rise in the modern, challenging area of far-field speech processing. The developed methods for each problem, namely (a) multichannel speech enhancement, (b) voice activity ... -
Multi-room speech activity detection using a distributed microphone network in domestic environments
(2015)Domestic environments are particularly challenging for distant speech recognition: reverberation, background noise and interfering sources, as well as the propagation of acoustic events across adjacent rooms, critically ... -
Multichannel speech enhancement using MEMS microphones
(2015)In this work, we investigate the efficacy of Micro Electro-Mechanical System (MEMS) microphones, a newly developed technology of very compact sensors, for multichannel speech enhancement. Experiments are conducted on real ... -
Room-localized speech activity detection in multi-microphone smart homes
(2019)Voice-enabled interaction systems in domestic environments have attracted significant interest recently, being the focus of smart home research projects and commercial voice assistant home devices. Within the multi-module ...
