Engineering with departmental honors. He went on to Brown University in Providence, Rhode Island to study signal processing and began research on microphone arrays. He received a Master of Science degree in Electrical Engineering in 1993 and continued to pursue his work towards a Doctor of Philosophy degree. While a student at Brown, he held several(More)
A major problem for speech recognition systems is relieving the talker of the need to use a close-talking, head-mounted or a desk-stand microphone. A likely solution is the use of an array of microphones that can steer itself to the talker and can use a beam-forming algorithm to overcome the reduced signal-to-noise ratio due to room acoustics.

A frequency-domain delay estimator has been used as the basis of a microphone-array talker location and beamforming system Brandstein, M. (1990)], including a shorter analysis window and greater accuracy at lower computational cost, it has the disadvantage that since delays between microphone pairs are estimated independently of one another, there is(More)
