Abstract:

This thesis investigated the feasibility of voice data entry for imagery intelligence order of battle reporting. Time, accuracy, and efficiency were measured for 20 subjects in an experiment physically simulating the use of a light table, optics, and an interactive computer system for reporting. A Threshold Technology Inc. T600 voice recognition system was used for a large, unstructured vocabulary 255 words of unclassified SovietWarsaw Pact equipment names, alphanumerics, and editing commands. The T600 recognition accuracy for this experiment was 97.0 without rejects, and 95.5 with rejects. Buffered voice and unbuffered voice modes of the T600 were evaluated with typing buffered voice was 58 faster, and unbuffered voice 41 faster than typing. Voice was also found to be as accurate as typing for writing short order of battle reports. Finally, subjects preferred voice for several criteria evaluated before and after the experiment.
