Abstract:

This report describes the design, principles of operation, and performance characteristics of an Advanced Development Model of a voice recognition system VRS which can serve to input cartographic data to a computer. The completed system has been installed at the Defense Mapping Agency Aerospace Center DMAAC at St. Louis, MO, for evaluation and testing. The VRS is intended for use in entering by voice cartographic data to the Digital Landmass System DLMS Data Base. It was designed to satisfy the DMAAC product specifications. The software developed for the VRS includes two complete stand-alone programs. Performance tests conducted at TTI disclosed an average system word recognition accuracy of just under 99 percent for five talkers. The recognition tests were conducted by the use of tape recordings. These tape recordings were made during a previous contract involving cartographic data entry. Each person spoke approximately 536 words after uttering five training repetitions. The test results were virtually identical to those obtained during the previous contract.
