Minimizing echo due to speaker-to-microphone coupling changes in an acoustic echo canceler
An endpoint receives audio from a remote endpoint. A first signal corresponding to the audio is received at an adaptive filter, and a filtered signal is generated. First audio is emitted at a loudspeaker based on the first signal. A microphone collects second audio which is based on the first audio. The microphone signal emits a signal based on the second 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 raised.
