Abstract

An aircraft information retrieval system comprises a digital audio panel operable to receive an analog voice signal representing a request for the display of graphical information and convert the analog voice signal to a digital voice signal. The system further comprises a remote audio processor coupled to the digital audio panel, the remote audio processor configured to receive the digital voice signal. The remote audio processor is further operable to determine an information request from the digital voice signal. A command processor, coupled to the remote audio processor, is configured to receive the information request and to retrieve the graphical information.

Claims

1. A method for requesting graphical navigational information for viewing on a display comprising:

receiving a voice recognition pattern;

receiving a digitized speech request to display the graphical navigational information;

converting the digitized speech request to an interpreted command using the voice recognition pattern; and

retrieving the graphical navigational information from a database using the interpreted command.

2. The method of claim 1 further comprising the step of displaying the graphical navigational information on a display.

3. The method of claim 2 further comprising the step of manipulating the displayed information in response to a user'"'"'s command.

4. The method of claim 1 wherein the step of receiving a voice recognition pattern further comprises retrieving the voice recognition pattern stored on a memory card.

5. The method of claim 1 further comprising receiving an indication that the digitized speech request is related to graphical navigational data.

6. The method of claim 1 wherein the step of receiving a voice recognition pattern further comprises retrieving a locally stored voice recognition pattern.

7. The method of claim 1 wherein the step of receiving a digitized speech request further comprises:

receiving an analog speech request;

converting the analog speech request to a digitized speech request; and

receiving the digitized speech request at an audio processor.

8. An aircraft information retrieval system comprising:

removable memory means adapted to store voice patterns;

audio processing means for receiving a voice signal representing a request for the display of graphical navigational information;

the audio processing means further configured for determining an information request from the voice signal and adapted to at least selectively couple with the removable memory means and retrieve a voice pattern stored on the removable memory means; and

display means for displaying the graphical navigational information.

9. The system of claim 8 wherein the audio processing means utilizes voice recognition software to interpret the voice signal.

10. The system of claim 9 wherein the voice recognition software uses a voice pattern of a user to assist in interpreting the voice signal.

11. The system of claim 10 wherein the audio processing means uses a voice pattern from the removable memory means.

12. The system of claim 10 wherein at least one voice pattern is provided with the voice recognition software.

13. The system of claim 8 further comprising a map database coupled to the audio processing means, the map database comprising a plurality of maps.

14. The system of claim 8 further comprising a switch coupled to the audio processing means, the switch is configured to allow the determination of the information request.

15. The system of claim 14 wherein the switch, when deactivated, allows voice signals to be sent to other aircraft components.

16. The system of claim 8 further comprising a headset coupled to the audio processing means, the headset outputting an analog voice signal to the audio processing means.

17. The system of claim 16 wherein the headset outputs a digitized voice signal to the audio processing means.

18. A device for recognizing requests for display of graphical navigational information for an airplane the device comprising:

a database containing the graphical navigational information;

a voice recognizer coupled to the database and configured to receive a digital voice request for display of the graphical navigational information, to recognize the digital voice request as a request to retrieve the graphical navigational information, and to retrieve the graphical navigational information from the database.

19. The device of claim 18 wherein a voice recognition program executing on the voice recognizer converts the digital voice request to the request to retrieve the graphical navigational information.

20. The device of claim 19 wherein the voice recognition uses a prerecorded voice pattern of a pilot to convert assist in converting the digital voice request to the request to retrieve the graphical navigational information.
