1. A processor, comprising circuitry configured to: receive far-end and near-end audio signals; detect voice activities from the audio signals using a voice activity detection algorithm; detect sound activities from the audio signals using a sound activity detection algorithm; detect a sound position from the audio signals using an acoustic source localization algorithm; receive data indicative of a region of interest; when the voice activity detection algorithm indicates voice activities at a same time that the sound activity detection algorithm indicates sound activities, determine whether the sound position is in the region of interest; determine that an audio event in the audio signals is an interference event in response to the sound position being outside of the region of interest; and generate a mute or unmute indication based on whether the audio event being the interference event.
