Comparative experiments: speech recognizers for ATC simulations
Innovative multimedia techniques like speech recognition are in development and could be used for real-time ATC simulation facilities. The specific ATC command language, with its restrictive structure, may be more applicable to speech recognition systems. Industry is offering speech recognition devices based upon different concepts and very high recognition quality is reported. The aim of the experiments reported upon was to examine the recognizers under conditions as closely as possible to real-time ATC simulations. For this reason, speech recordings were conducted during live EEC real-time simulations manned by experimented controllers of different nationalities and diverse native languages.
