Voice Data Entry in Air Traffic Control.

Abstract

Two major experiments and a number of subsidiary pilot studies were conducted to assess the potential operational utility of state-of-the-art word recognition technology in air traffic control applications. Experiment I, employing 12 operators or 'talkers', secured baseline data representing the inherent 'best case' recognition accuracy of the system. Three of the subvocabularies of an operational data entry language were tested exhaustively to a total of over 46,000 spoken words. On the average, across all speakers and all three subvocabularies, only 1 percent of the words spoken were erroneously recognized. Subsequently 'tuning' of the recognition algorithm reduced the error rate to less than 0.4 percent. Experiment II compared the quality and efficiency of the voice system versus the existing keyboard method of entering complete operational messages.
