Abstract

A control system for aiding the operator of a vehicle or platform, such as an aircraft. The system includes a receiver adapted to receive a voice command from a controller located remotely from the vehicle or platform. A speech recognition device is coupled to the receiver and adapted to compare the voice command to speech recognition templates of known voice commands. A match between the voice command and a speech recognition template is indicative of informational content of the voice command. A display device coupled to the speech recognition device displays to the operator of the vehicle or platform a visual representation of the informational content of the voice command.

Claims

1. A control system for aiding the operator of a platform, the system comprising:

a receiver adapted to receive a voice command from a controller located remotely from the platform;

a speech recognition device coupled to the receiver and adapted to compare the voice command to speech recognition templates of known voice commands, wherein a match between the voice command and a speech recognition template is indicative of informational content of the voice command; and

a display device coupled to the speech recognition device and adapted to display to the operator of the platform a visual representation of the informational content of the voice command.

2. The control system of claim 1, wherein the display device displays to the operator of the platform a textual representation of the informational content of the voice command.

3. The control system of claim 2, wherein the voice command from the operator is in a first language and the textual representation of the informational content of the voice command is in a second language.

4. The control system of claim 1, wherein the display device displays to the operator of the platform an icon representation of the informational content of the voice command.

5. The control system of claim 1 and further comprising a comparison device coupled to the speech recognition device and adapted to compare the informational content of the voice command received from the controller to environmental conditions associated with the platform, wherein the comparison device generates a warning signal if the comparison indicates inconsistency between the informational content of the voice command and the environmental conditions associated with the platform.

6. The control system of claim 5, wherein the environmental conditions associated with the platform include control settings of controls of the platform.

7. The control system of claim 5, wherein the comparison device is further adapted to compare the informational content of the voice command received from the controller and the environmental conditions associated with the platform to a confirmation of the voice command made by the platform operator, wherein the comparison device generates a warning signal if the comparison indicates inconsistency between the informational content of the voice command, the environmental conditions associated with the platform and the confirmation of the voice command.

8. The control system of claim 1 and further comprising a digital encoder coupled between the receiver and the speech recognition device, wherein the digital encoder receives from the receiver a signal corresponding to the voice command, digitizes the received voice command signal, and stores the digitized voice command signal in memory, and wherein the speech recognition device compares the digitized voice command signal to digital speech recognition templates of known voice commands.

9. The control system of claim 8 and further comprising:

a platform operator input device adapted to generate a control signal at the operator'"'"'s request; and

a data-to-speech converter coupled to the digital encoder and to the operator input device, wherein upon receipt of the control signal generated by the operator input device at the operator'"'"'s request, the data-to-speech converter converts the stored digitized voice command signal into a speech message thereby repeating the voice command from the controller.

10. The control system of claim 9, wherein using the operator input device the operator of the platform can control the speed at which the voice command is repeated by the data-to-speech converter.

11. An aircraft avionics system comprising:

an RF receiver adapted to receive a voice command from a controller located remotely from the aircraft;

a digital encoder coupled to the RF receiver and adapted to digitize and store the voice command;

a pilot input device adapted to generate control signals at the pilot'"'"'s request; and

a data-to-speech converter coupled to the digital encoder and to the pilot input device, wherein upon receipt of a control signal generated by the input device at the pilot'"'"'s request the data-to-speech converter converts the stored digitized voice command into a speech message format, thereby repeating the voice command to optimize the pilot'"'"'s comprehension of the voice command.

12. The aircraft avionics system of claim 11, wherein using the input device the pilot can control the speed at which the voice command is repeated by the data-to-speech converter.

13. The aircraft avionics system of claim 11, and further comprising:

a speech recognition device coupled to the digital encoder and adapted to compare the digitized voice command to speech recognition templates of known voice commands, wherein a match between the digitized voice command and a speech recognition template is indicative of informational content of the voice command; and

a display device coupled to the speech recognition device and adapted to display to the pilot a visual representation of the informational content of the voice command.

14. The aircraft avionics system of claim 13, wherein the display device displays to the pilot a textual representation of the informational content of the voice command.

15. The aircraft avionics system of claim 13, wherein the display device displays to the pilot an icon representation of the informational content of the voice command.

16. The aircraft avionics system of claim 13 and further comprising a comparison device coupled to the speech recognition device and adapted to compare the informational content of the voice command received from the controller to environmental conditions associated with the aircraft, wherein the comparison device generates a warning signal if the comparison indicates inconsistency between the informational content of the voice command and the environmental conditions associated with the aircraft.

17. The aircraft avionics system of claim 16, wherein the environmental conditions associated with the aircraft include control settings of avionics controls of the aircraft.

18. A method of communicating a controller'"'"'s commands to the pilot of an aircraft, the method comprising:

receiving a voice transmission from the controller, the voice transmission containing a voice command;

digitally encoding the voice command;

comparing the digitally encoded voice command to known digital voice command templates, wherein a match between the digitally encoded voice command and a known digital voice command template is indicative of informational content of the voice command; and

after matching the digitally encoded voice command with a digital voice command template, displaying in a visual format the informational content of the voice command to thereby optimize the pilot'"'"'s comprehension of the voice command.

19. The method of claim 18 and further comprising:

comparing the informational content of the voice command to known environmental conditions; and

generating an alert message if the comparison of the informational content of the voice command to the known environmental conditions indicates a problem.

20. The method of claim 18 and further comprising:

repeating the voice command at the pilot'"'"'s request by using a data-to-speech converter to convert the digitally encoded voice command into a speech format message.
