To adapt to the requirements posed by rapidly changing world-wide threats, modern military systems must harness advanced technology in ways that significantly improve operational effectiveness. Many critical systems are interactive, and the ability of user to interact with such systems could be improved by the addition of spoken language interfaces to facilitate humanmachine interaction, increase productivity, and reduce training time. Our goals are to develop usable SLSs that exhibit the following advances 1 at least an order of magnitude increase in speed, with higher accuracy 2 a four-fold reduction in the overall understanding error rate 3 a vocabulary of up to 10, 000 words 4 a highly interactive user interface capable of mixed initiative dialogue, system feedback, and user corrections and additions 5 a flexible system capable of transparently adapting to a new user 6 a modular system easily portable to new applications and sites and 7 a system implementable in real-time on COTS hardware.
