Selective audio canceling

摘要

The implementations described include an audio canceling device that receives and audio signal from within an environment, identifies desired and undesired audio from the received audio signal and generates an attenuation-signal for use in canceling out or reducing the volume of the undesired audio at a canceling location. In addition, the audio canceling device, may determine a time delay before the attenuation-signal should be transmitted from an output based on a distance between the undesired audio source location and the canceling location and a distance between the output and the canceling location.

1. A method comprising:
under control of one or more computing devices configured with executable instructions,
receiving a series of images of a user located within an, environment;identifying visual cues within the image;comparing the visual cues with a repository that includes stored facial movements of the user to determine stored facial movements of the user that correspond with the visual cues;creating a representative undesired audio signal based at least in part on stored audio signals that correspond with the determined stored facial movements;determining a time delay that is to elapse before the representative undesired audio signal is transmitted from an output such that the representative undesired audio signal will arrive at a canceling location so that an undesired audio signal generated by the user is canceled at the canceling location by the representative undesired audio signal, wherein the output and the canceling location are located within the environment; andtransmitting the representative undesired audio signal from the output after the time delay has elapsed so that the undesired audio signal is canceled at the canceling location.
