Abstract :
We propose in this paper an array of microphones which achieves good performance in double talk situations. By a subspace tracking procedure, we jointly identify the acoustic paths from the speech and echo sources. With an adaptive beamformer constrained over these paths, we properly recover the original speech, cancel the echo and reduce the background noise. Simulations made with real data confirm the efficiency of this array
