A frequency-domain delay estimator has been used as the basis of a microphone-array talkerlocation and beamforming system [Brandstein, M.S., and Silverman, H.F., Technical Report LEMS116,(1993)] . While the estimator has advantages over previously employed correlation-based delayestimation methods [Silverman, H.F. and Kirtman, S.E., Computer Speech and Language, 6, 129152(1990)], including a shorter analysis window and greater accuracy at lower computational cost,it has the disadvantage...
