Patent attributes
Devices, methods, and systems for detecting wake words and audio commands that should be disregarded are disclosed. In some instances, a local device may receive a wake word or audible command transmitted or uttered in a television or radio advertisement, program, broadcast, etc. In these instances, the local device should disregard such wake words and audible commands, as they are not from a user of the local device. To detect such wake words and commands, audio fingerprinting and speech recognition techniques may be used to determine whether the wake word and/or command substantially matches the audio of a known television or radio advertisement, program, broadcast, etc. If the wake word and/or command substantially matches, the local device may then disregard the command.
