An electronic device includes one or more sensors and one or more processors. The one or more sensors receive a first audio input defining a process initiation command and initiate, in response to the process initiation command, a process. Thereafter, the one or more sensors receive a second audio input defining a process cessation command. The one or more processors determine whether one or more substantially matching audio characteristics are present in both the first audio input and the second audio input. Where they are absent from one of the first audio input or the second audio input, the one or more processors ignore the process cessation command and continuing the process. Where they are present, the one or more processors cease the process in response to the process cessation command.
