ABSTRACT:
A voice activated programmer (10) controlling the operation of an appliance such as a television (T) or VCR (V). A receiver (12) operating in the audio frequency range receives an audio command spoken by a person. A converter (20) converts the audio input to the receiver into an electrical signal. A processor (22) processes the electrical signal to determine if the person who spoke is a person previously authorized to operate the appliance. A controller (32) performs the function requested by the person who spoke only if the person is a previously authorized person. If more than one person directs a command to the programmer, the sequence with which the commands are executed is determined based on a voice hierarchy.
