Abstract
The present invention relates to an alarm management system intended to be carried onboard an aircraft. More precisely, the invention is aimed at improving the certainty level relating to the integrity of the announcements of faults or information intended for the pilot and based on voice syntheses. For this purpose, the present invention proposes a device and a method for detecting the digital origin of an analog signal providing a validity signal (VAL) enabling the voice announcements made to the pilot to be rendered secure.
