Abstract

The invention is a method and apparatus for controlling electronic devices from a remote location. The method and apparatus utilizes a remote control device which receives and transmits voice commands as electrical signals to at least one controlled device having a recognition processor which converts received electrical signals to pattern data and compares that pattern data with data stored in the processor. The invention may incorporate the use of a recorder for recording electrical signals in the remote or controlled device and may further include a teaching circuit for retrieving and reproducing voice commands as visual or audio prompts as needed. The invention may be adapted to control multiple controlled devices in coordination so that each coordinated device is made to perform the same or a different function in response to a single voice command is disclosed.

Claims

1. A voice command remote control system comprising:

a remote control device for controlling a household appliance controlled device comprising;

a transducer that converts sound of an audio voice command to an electrical signal;

a transmitter that transmits said electrical signal to a first controlled device, wherein said first controlled device comprises;

a recognition processor that converts said electrical signal to pattern data and compares said pattern data with a plurality of sets of stored pattern data to recognize said audio voice command as corresponding to one of the sets of the stored pattern data;

comprising said first controlled device and wherein said first controlled device performs a preset function corresponding to said audio voice command in response to recognition of said audio voice command; and

a recorder that records said electrical signal.

2. The voice command remote control system of claim 1, wherein the recorder is located in the remote device.

3. The voice command remote control system of claim 1, wherein the recorder is located in the controlled device.

4. The voice command remote control system of claim 2, wherein said remote control device further comprises a repeat button and wherein said recorder is activated to reproduce a last recorded electrical signal for transmission to a first controlled device responsive to activation of said repeat button.

5. The voice command remote control system of claim 4, further comprising a record button and wherein said recorder is activated to record said electrical signals responsive to activation of said record button.

6. The voice command remote control system of claim 4, wherein said recorder is voice-activated and wherein said recorder is activated to record said electrical signals responsive to voice-activation.

10. The voice command remote control system of claim 1, wherein said first controlled device further comprises a transmitter for generating and transmitting a control signal to a second controlled device.

11. The voice command remote control system of claim 10, further comprising a second controlled device which receives said control signal and performs a preset function responsive to said control signal.

7. A voice command remote control system comprising:

a remote control device for controlling a household appliance controlled device comprising;

a transducer that converts sound of an audio voice command to an electrical signal;

a transmitter that transmits said electrical signal to a first controlled device, wherein said first controlled device comprises;

a recognition processor that converts said electrical signal to pattern data and compares said pattern data with a plurality of sets of stored pattern data to recognize said audio voice command as corresponding to one of the sets of the stored pattern data;

comprising said first controlled device and wherein said first controlled device performs a preset function corresponding to said audio voice command in response to recognition of said audio voice command; and

wherein said first controlled device further comprises a transmitter for generating and transmitting a second electrical signal to a second controlled device.

8. The voice command remote control system of claim 7, further comprising a second controlled device which receives said second electrical signal and has a recognition processor that converts said second electrical signal to pattern data and compares said pattern data with a plurality of sets of stored pattern data to recognize said audio voice command as corresponding to one of the sets of the stored pattern data.

9. The voice command remote control system of claim 8, wherein said second controlled device further comprises a transmitter for generating and transmitting a third electrical signal to a third controlled device.

12. A method of controlling at least one controlled device from a remote location comprising the steps of:

a. receiving an audio voice command into a remote control device;

b. converting said audio voice command to an electrical signal in said remote control device;

c. transmitting said electrical signal from said remote control device to a first controlled device;

d. converting said electrical signal into pattern data within said first controlled device;

e. comparing said pattern data with a plurality of sets of pattern data stored within the first controlled device to recognize the audio voice command as corresponding to one of the sets of the stored pattern data; and

f. recording the electrical signal on a recorder located within the remote control device.

13. The method of claim 12, further comprising the step of retrieving a last recorded signal from the recorder and transmitting said last recorded signal to said first controlled device responsive to activation of a repeat button.

14. The method of claim 13, wherein the electrical signal is recorded by pressing a record button to activate a recorder and releasing the record button to stop recoding.

15. The method of claim 14, wherein the electrical signal is recorded by speaking into a voice-activated recorder.

16. A method of controlling at least one controlled device from a remote location comprising the steps of:

a. receiving an audio voice command into a remote control device;

b. converting said audio voice command to an electrical signal in said remote control device;

c. transmitting said electrical signal from said remote control device to a first controlled device;

d. converting said electrical signal into pattern data within said first controlled device;

e. comparing said pattern data with a plurality of sets of pattern data stored within the first controlled device to recognize the audio voice command as corresponding to one of the sets of the stored pattern data; and

f. transmitting a second electrical signal from said first controlled device to a second controlled device.

17. The method of claim 16, further comprising the step of converting said second electrical signal into a second set of pattern data within said second controlled device.

18. The method of claim 17, further comprising the step of comparing said second set of pattern data with a plurality of sets of pattern data stored within said second controlled device to recognize said audio voice command as corresponding to one of said sets of pattern data stored within the second controlled device.

19. The method of claim 18, further comprising the step of transmitting a third electrical signal from said second controlled device to a third controlled device.

20. The method of claim 16, further comprising the step of generating and transmitting a control signal from said first controlled device to a second controlled device.

21. The method of claim 20, further comprising the step of performing a present function corresponding to said audio voice command in said second controlled device in response to recognition of said audio voice command.

22. The method of claim 19 wherein said first, second, and third controlled devices are independently selected from the group consisting of telephone answering devices, television sets, stereos, video cassette recorders, compact disk players, cassette tape players, and digital video disk players.

23. The method of claim 22 wherein at least one of said first, second, and third controlled devices comprises a telephone answering device.

24. The method of claim 22 wherein at least one of said first, second, and third controlled devices comprises a television set.

25. The method of claim 24 further comprising the step of recording the electrical signal on a recorder located within the remote control device.

26. The method of claim 25 further comprising the step of retrieving a last recorded signal from the recorder and transmitting said last recorded signal to said first controlled device responsive to activation of a repeat button.
