During taxiing, an Electronic Flight Bag (EFB) showing airport and route-data can support pilots. In the present study, the possibility of using a Voice Recognition System (VRS) to enable pilots to enter route instructions, for usage in situations where digital data link is not available, was investigated. The potential of techniques that utilize information on airport layout to detect and correct voice recognition errors was explored. Experiment I investigated the accuracy rates that can be achieved with the basic VRS. Although high, the resulting accuracy was insufficient, for safety reasons as well as user-acceptance of the system. A configurable system that interprets user utterances based on possible taxi routes on the airport, was designed and implemented. Experiment II explored the potential improvement of the different configuration options on error detection and correction performance. With one of the configurations, an increase of 42% in overall recognition rates was achieved.
