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.

Claims

1. A voice activated programmer for controlling the operation of an appliance comprising:

a receiver operating in the audio frequency range to receive commands spoken by a person;

a converter converting commands received by the receiver into an electrical signal;

a processor processing the electrical signal to determine if the person who spoke is a person previously authorized to operate the appliance;

a controller performing the function requested by the person who spoke only if the person is a previously authorized person; and

,

a voice programmer for initially processing each authorized voice to which said programmer is to respond, the voice programmer including a memory for storing voice indicia by which said authorized voice is to be later recognized, means establishing a hierarchy of voices so if more than one person directs a command at the programmer, the programmer can determine a sequence by which commands will be responded, and appliance selection means for selecting from which of a plurality of appliances with which said programmer may be used, commands spoken by an authorized person are directed.

2. The programmer of claim 1 further inclding a transmitter for transmitting a command signal from said controller to said appliance, said appliance including a receiver for receiving said signal.

3. The programmer of claim 1 wherein said voice programmer further includes command selection means by which specific commands which a person authorized to operate an appliance can use is limited to selected commands.

4. The programmer of claim 3 wherein said voice programmer flrher includes command timing means by which intervals during which the command selection means is engaged is limited to selected time intervals.

5. The programmer of claim 4 wherein said voice programmer further includes voice timing means for determining the length of time between which separate persons have voiced commands for the same appliance and for authorizing execution of the later command only if a predetermined period of time has elapsed since the previous command was spoken.

6. The programmer of claim 5 wherein said voice programmer further includes language means for allowing authorized persons to command an appliance is a plurality of selected languages by which one speaker can issue a command for an appliance in one language, and another authorized person can issue a command for the same appliance in a different language, and said programmer will respond to each command.

7. The programmer of claim 1 wherein said programmer further includes means for deleting authorized voices so a person who is no longer authorized cannot issue commands for an appliance.

8. The programmer of claim 1 wherein said controller includes a command formatter formatting each command to which an appliance is to respond in a format compatible with a receiver of the appliance.

9. The programmer of claim 8 wherein said controller further includes a signal generator producing a command signal directed to said appliance, and a modulator responsive to an input from said command formatter to modulate said command signal.

10. The programmer of claim 9 wherein said signal generator generates a radio frequency signal.

11. The programmer of claim 9 wherein said signal generator generates an infrared signal.

12. A voice activated programmer for controlling the operation of an appliance comprising:

a receiver operating in the audio frequency range to receive a command for said appliance spoken by a person;

a voice programmer for authorizing persons who may use said programmer to command said appliance, said voice programmer initially processing each authorized voice to which said programmer is to respond, said voice programmer including a memory for storing voice indicia by which said authorized voice is to be later recognized, and said voice programmer including means establishing a hierarchy of voices so if more than one person directs a command at the programmer, the programmer can determine a sequence by which commands will be responded;

a processor processing a received command and determining if the person who spoke is a person authorized to operate the appliance; and

,

means responsive to a verification from said processor that the person is authorized to command the requested function of said appliance.

13. The programmer of claim 12 further including a transmitter for transmitting a command signal from said controller to said appliance, said appliance including a receiver for receiving said signal.

14. The programmer of claim 13 wherein said programmer further includes means deleting authorized voices so a person who is no longer authorized cannot issue commands for an appliance.

15. The programmer of claim 12 wherein said voice programmer further includes appliance selection means for selecting from which of a plurality of appliances with which said programmer may be used, commands spoken by an authorized person can be directed.

16. The programmer of claim 12 wherein said voice programmer further includes language means for allowing authorized persons to command an appliance is a plurality of selected languages by which one speaker can issue a command for an appliance in one language, and another authorized person can issue a command for the same appliance in a different language, and said programmer will respond to each command.

17. A voice activated programmer for controlling the operation of an appliance comprising:

a receiver operating in the audio frequency range to receive a command for said appliance spoken by a person;

a voice programmer for authorizing persons who may use said programmer to command said appliance, said voice programmer including means by which execution of said received commands is limited to selected time intervals;

a processor processing a received command and determining if the person who spoke is a person authorized to operate the appliance;

and, means responsive to a verification from said processor that the person is authorized to command the requested function of said appliance.

18. The voice activated programmer of claim 17 wherein said voice programmer further includes voice timing means for determining the length of time between which separate persons have voiced commands for the same appliance and for authorizing execution of the later command only if a predetermined period of time has elapsed since the previous command was spoken.
