Abstract: Methods and systems are provided for validation of speech commands from an aircraft pilot. The method comprises receiving a speech command from the aircraft pilot with a voice communication device that is part of a cockpit system. Next, the speech command is decoded into a computer readable format. The decoded speech command is then checked against the present aircraft state as indicated by avionic sensors of the aircraft and against an approved pre-condition that is stored in a pre-condition database. The decoded speech command is validated if the decoded speech command is consistent with the present aircraft state and consistent with the approved pre-condition. An input to the cockpit system is updated to execute the speech command from the aircraft pilot if the decoded speech command is validated.

Abstract: A voice recognition system in an aircraft is provided. The voice recognition system includes: a voice recognition controller configured to receive a voice command from a flight crew member voice interface, convert the voice command to an avionics system command, and forward the avionics system command to an avionics system for execution. The voice recognition system further includes an application controller configured to: receive the avionics system command that has been converted from the voice command; determine whether the avionics system command can be performed; cause the avionics system command to be performed when it is determined that the avionics system command can be performed; and when it is determined that the avionics system command cannot be performed, generate a message that provides a reason why the avionics system command cannot be performed and cause the message to be displayed on a display device and/or annunciated on an aural device.
