Speech Recognition and AI Help Take the Pressure off Aircrew
Air accidents have decreased in recent years, but when they do occur, the crew's workload is usually at its highest level. Therefore, augmenting crew performance during high workload periods is of great importance and can help maintain flight safety.
Aircrew workloads peak when faced with a combination of unpredictable situations: meteorological conditions; high-density traffic; system failures; and flight operations like take-off, climb, descent, approach and landing. The amount of information and number of actions that need to be processed by the crew may become unmanageable, affecting flight safety. The EU-funded VOICI project addressed this threat by developing an intelligent 'natural crew assistant' for the cockpit environment. The system comprises three main technologies, namely sound recording, speech recognition and artificial intelligence. This includes a cockpit-embedded speech-processing system that understands aviation terminology, as well as an array of low-noise optical microphones and optimised array processing for it. The VOICI system also features a new and more efficient speech synthesis, adapted to aviation terminology and noise levels.
