The microphone signal emits a signal bad on the cond audio. The filtered signal is subtracted from microphone signal to generate an adapted signal, the adapted signal having an energy level. The adapted signal is then transmitted to a double-talk detector, the double-talk detector configured to allow transmission of the adapted signal to the remote endpoint when the energy level of the adapted signal exceeds an energy threshold. The degree of cross-correlation between the first signal and the adapted signal is determined (iteratively). If the cross-correlation exceeds a cross-correlation threshold, the energy threshold of the double-talk detector is raid.
