Abstract :
This paper proposes a new double-talk detection method with double filters. Noting that the coefficients of adaptive filter can´t converge rapidly at the end of double-talk, we present a double-talk detection based on dual-auxiliary filters of different taps. It is compared with the method of double-filter. It turns out that the method we proposed can not only make the adaptive filter coefficients converge fast but also track the echo path well.
