US Patent 11430447 Voice activation based on user recognition

A device for voice activation includes one or more processors. The one or more processors are configured to receive, via one or more microphones, a keyword and a first command spoken by a first user. The one or more processors are also configured to, subsequent to receiving the first command, receive a second command via the one or more microphones without an intervening receipt of the keyword. The one or more processors are further configured to, based at least in part on determining that the second command is spoken by the same first user, selectively process the second command.
