Using Speech Analysis in Voice Communication A new approach to improve Air Traffic Management Security

This document describes the concept of an air traffic management security system and current validation activities. This system uses on one hand speech analysis techniques to verify the speaker authorization and measure the stress level within the air-ground voice communication between pilots and air traffic controllers; on the other hand it monitors the current air traffic situation. The purpose of this system is to close an existing security gap by using this multi-modal approach. First validation results are discussed at the end of this paper.
