1. A computer-implemented method comprising: ascertaining, from one or more images of a location, that a person at the location is speaking; detecting, by at least one of a double-talk detector of an acoustic echo processor or by a voice activity detector of the acoustic echo processor, that an audio signal associated with a voice is generated by a microphone at the location; determining, by the acoustic echo processor, a confidence score indicating a likelihood that the audio signal is associated with the person at the location; adjusting, by the acoustic echo processor, the confidence score based at least in part on the one or more images depicting the person at the location engaged in speaking; determining that the confidence score exceeds a threshold; changing, by the acoustic echo processor, adaptation of a filter of the acoustic echo processor based at least in part on the confidence score exceeding the threshold and the detecting the audio signal associated with the voice; and removing, at least in part, background noise from the audio signal based at least in part on the confidence score exceeding the threshold, wherein an amount of the background noise removed from the audio signal is based at least in part on a known echo path of the location.
