Automatic collection and processing of voice data from air-traffic communications

ATCO2 project aims at developing a unique platform allowing to collect, organize and pre-process air-traffic control (voice communication) data from air space. Preliminarily the project will consider the real-time voice communication between air-traffic controllers and pilots available either directly through publicly accessible radio frequency channels, or indirectly from air-navigation service providers (ANSPs). In addition to the voice communication, the contextual information available in a form of metadata (i.e. surveillance data) will be exploited.
