Robust Speaker Localization in Meeting Room Domain
2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007Speech signal is perturbed in real environments due to room acoustics and noise sources. The speech wavefront is received by a microphone array, which is used to determine the wavefront direction of arrival (DOA). DOA estimates from several spatially separated arrays are used to locate the speaker. Array channels may sometimes be corrupted by noise. In

Speaker localization and speech extraction with the EAR sensor
2009 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2009This paper presents the Embedded Audition for Robotics (EAR) project internally developed at LAAS and its application to speaker localization and extraction. Hardware and software issues are first thoroughly depicted, concerning the development of an auditory sensor based on an array of microphones, a homemade dedicated acquisition chain and a FPGA ...

Smart Room: Participant and Speaker Localization and Identification
Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006Our long-term objective is to create smart room technologies that are aware of the users presence and their behavior and can become an active, but not an intrusive, part of the interaction. In this work, we present a multimodal approach for estimating and tracking the location and identity of the participants including the active speaker.

Speaker localization and cancellation for improving social attention
Proceedings of the ACM/IEEE 4th International Conference on Cyber-Physical Systems, 2013Autistic individuals suffer from sensory impairment and can become frustrated in conversational settings involving multiple people [3]. For this reason, many choose to avoid certain social settings filled with different sounds. Such behavior only adds to their lack of necessary social skills and inhibits them from joining others in regular conversation.

Performance of speaker localization using microphone array
International Journal of Speech Technology, 2016Speaker localization is a technique to locate and track an active speaker from multiple acoustic sources using microphone array. Microphone array is used to improve the speech quality of recorded speech signal in meeting room and other places. In this work, the time delay estimation between source and each microphone is calculated using a localization ...
