A system and method are provided for programming a flight management system in response to a voice input. The voice input is validated (the pilot spoken vocabulary is thereby filtered (e.g., adapted) to improve recognition accuracy and reduce false positives) by comparing the current operational state of the aircraft (for example, climb, level flight, descent, speed, altitude, and heading), operation validities and availabilities (for example, operations allowed and not allowed) based on the flight management system planned and predicted lateral and vertical trajectory of the flight route (flight plan) from origin/present position to destination, and the requested action being taken.
