An experiment in voice data entry for imagery interpretation reporting.

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. Te00 voice recognition system was used for a large, unstructured vocabulary (255 words) of unclassified Soviet/Warsaw Pact equipment names, alphanumerics , and editing commands. The Te00 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 56% faster, end 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.
