20210158831 | METHOD AND APPARATUS FOR DETERMINING PERIODS OF EXCESSIVE NOISE FOR RECEIVING SMART SPEAKER VOICE COMMANDS - Methods and systems for determining periods of excessive noise for smart speaker voice commands. An electronic timeline of volume levels of currently playing content is made available to a smart speaker. From this timeline, periods of high content volume are determined, and the smart speaker alerts users during periods of high volume, requesting that they wait until the high-volume period has passed before issuing voice commands. In this manner, the smart speaker helps prevent voice commands that may not be detected, or may be detected inaccurately, due to the noise of the content currently being played. | 2021-05-27 |
