Abstract :
Microphone arrays can capture desired signals and attenuate interfering noise and reverberation in multipath environments. Hands-free speech technologies can therefore be supported using microphone arrays. This article considers delay-and-sum beamformers, advanced array technology using matched-filters and hands-free speaker identification using microphone arrays
