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)
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 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)
N ational health expenditures this year are estimated at about US$1.5 trillion, or almost 15 percent of GDP, by the Centers for Medicare and Med-icaid Services (www.cms.gov). This comprises the largest service sector in the US economy. Moreover, cost increases are outpacing general inflation, so the health care industry is again under pressure to become(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)
