Abstract
Aspects of the present disclosure relate to distinguishing voice commands. One or more stored blocked directions of background voice noise from one or more audio output devices for a location of a voice command device are accessed. A voice input is received at the voice command device at the location and a determination is made that the voice input is received from a blocked direction. A status of an audio output device is queried to determine whether it is emitting audio. In response to a determination that the audio output device is currently emitting audio, an audio file is obtained from the audio output device, the audio file corresponding to a time when the voice input was received. The obtained audio file is compared with the received voice input. The received voice input is ignored if there is a substantial match with the obtained audio file.
