Airborne noise attenuation techniques in close curves from athens tramway operation
(2005)TRAM S.A. in order to manage the problem of "squealing noise", generated at close curves of its network, applies special bio-degradable grease on the side of the track way. A complete measurement campaign was executed with ... -
The Athena-RC system for speech activity detection and speaker localization in the DIRHA smart home
(2014)We present our system for speech activity detection and speaker localization inside a smart home with multiple rooms equipped with microphone arrays of known geometry and placement. The smart home is developed as part of ... -
ATHENA: A Greek multi-sensory database for home automation control
(2014)In this paper we present a Greek speech database with real multi-modal data in a smart home two-room environment. In total, 20 speakers were recorded in 240 one-minute long sessions. The recordings include utterances of ... -
Experiments in acoustic source localization using sparse arrays in adverse indoors environments
(2014)In this paper we experiment with 2-D source localization in smart homes under adverse conditions using sparse distributed microphone arrays. We propose some improvements to deal with problems due to high reverberation, ... -
Multi-microphone fusion for detection of speech and acoustic events in smart spaces
(2014)In this paper, we examine the challenging problem of detecting acoustic events and voice activity in smart indoors environments, equipped with multiple microphones. In particular, we focus on channel combination strategies, ... -
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 ... -
Room-localized spoken command recognition in multi-room, multi-microphone environments
(2017)The paper focuses on the design of a practical system pipeline for always-listening, far-field spoken command recognition in everyday smart indoor environments that consist of multiple rooms equipped with sparsely distributed ...
