This document presents the findings of a voice technology study that evaluated the potential of a speech-to-text and voice recognition system to support an Airway Facilities maintenance task. Researchers conducted the test at an Airport Surveillance Radar (ASR)-9 site at the William J. Hughes Technical Center. Thirteen Airway Facilities specialists completed the procedure twice, once with the voice technology system and again with a paper manual. The results showed no differences in task completion time or workload, suggesting that the voice technology system was no more time consuming or difficult to use than a traditional paper manual. The voice recognition rate was 86.6%. Questionnaire response showed that users found the voice technology system understandable, easy to control, and responsive to voice commands. When asked to compare voice technology to the use of a paper manual for the Air Traffic Control Beacon Interrogator (ATCBI)-5 maintenance procedure, study participants indicated that the voice technology system made the maintenance task easier to perform, was more efficient and effective than a paper manual, and would be better for handling large amounts of information. Researchers concluded that this study resulted in a successful demonstration of voice technology for the Airway Facilities maintenance procedure. It was recommended that further, more extensive studies be conducted using voice technology systems in a wider variety of Airway Facilities environments and tasks.
