Abstract

A first electronic device is provided. While a media content item provided by a media-providing service is emitted by a second electronic device that is remote from the first electronic device, the first electronic device receives, from the media-providing service, data that includes an audio stream that corresponds to the media content item. The first electronic device detects ambient sound that includes sound corresponding to the media content item emitted by the second electronic device. The first electronic device generates a cleaned version of the ambient sound, which includes: using the data received from the media-providing service to align the audio stream with the ambient sound; and performing a subtraction operation to subtract the audio stream from the ambient sound. The first electronic device detects a voice command in the cleaned version of the ambient sound.
