Abstract
A simple and robust signal processing solution to the acoustic echo control problem has been proposed recently in the literature. The solution is based on the purely statistical adaptation of an acoustic echo canceler and a postfilter for residual echo suppression. A sophisticated double talk detection is not required for the stability of this algorithm. We have realized a realtime prototype and in this paper we discuss the results of the performance evaluation in the car environment. It turns out that the main strengths of the proposed solution are the duplex ability (fast and robust adaptation in double talk), and the high degree of elegance and simplicity.
