One of the next big challenges in Automatic Speech Recognition (ASR) is the transcription of speech in meetings. This task is particularly problematic for current recognition technologies because, in most realistic meeting scenarios, the vocabularies are unconstrained, the speech is spontaneous and often overlapping, and the microphones are inconspicuously(More)
In 2012 NIST held the latest in an ongoing series of textindependent speaker recognition evaluations (SRE’s). The 2012 NIST Speaker Recognition Evaluation (SRE12) was the largest and most complex SRE to date, including over 100 million trials. Several aspects of SRE12 were new; most significantly, NIST released in advance of the evaluation target speaker(More)
A s an example of an early application that puts pervasive computing technologies directly in the service of improved quality of life for the elderly and that is " gracefully integrated with human users, " this inaugural installment looks at the assisted living complex constructed by Elite Care (www. elite-care.com). By building pervasive computing into the(More)
PERVASIVE computing 9 W hat if networked computers were as cheap as paper clips and could be attached to things as easily as a yellow sticky? We are about to find out, because such computers are being deployed across the world as you read this. They are, of course, Radio Frequency Identification tags—low-power, short-range communication devices that we can(More)
This paper describes the 1997 TREC-6 Spoken Document Retrieval (SDR) Track which implemented a first evaluation of retrieval of broadcast news excerpts using a combination of automatic speech recognition and information retrieval technologies. The motivations behind the SDR Track and background regarding its development and implementation are discussed. The(More)
This paper describes the 1998 TREC-7 Spoken Document Retrieval (SDR) Track which implemented an evaluation of retrieval of broadcast news excerpts using a combination of automatic speech recognition and information retrieval technologies. The motivations behind the SDR Track and background regarding its development and implementation are discussed. The SDR(More)
This paper presents a novel bird monitoring and recognition system in noisy environments. The project objective is to avoid bird strikes to aircraft. First, a cost-effective microphone dish concept (microphone array with many concentric rings) is presented that can provide directional and accurate acquisition of bird sounds and can simultaneously pick up(More)
Pervasive Computing devices, sensors, and networks, provide infrastructure for context aware smart meeting rooms that sense ongoing human activities and respond to them. This requires advances in areas including networking, distributed computing, sensor data acquisition, signal processing, speech recognition, human identification, and natural language(More)
PERVASIVE computing 9 W e are at the Royal Mile Pub in Silver Spring, Maryland. It is a restaurant and bar with about 20 tables specializing in a wide selection of beverages. Its dinner menu has specials along with many regular food items. Alex Malison is hosting a late evening dinner party for his sales representatives so they can see the order entry(More)
