CommandTalk is a spoken-language interface to synthetic forces in entity-based battlefield simulations, developed by SRI International under our DARPA-sponsored project on Improved Spoken-Language Understanding. The principal goal of CommandTalk is to let simulation operators interact with synthetic forces by voice in a manner as similar as possible to the way that commanders control live forces. CommandTalk currently interfaces to the ModSAF battlefield simulator and allows the use of ordinary English commands to :

• Create forces and control measures (points and lines)

• Assign missions to forces

• Modify missions during execution

• Control ModSAF system functions, such as the map display

CommandTalk was initially developed for LeatherNet, a simulation and training system for the Marine Corps developed under direction of the Naval Command, Control and Ocean Surveillance Center, RDT&E Division (NRaD). Recently CommandTalk has been extended to Navy, Air Force, and Army versions of ModSAF, to provide control of all synthetic forces in DARPA's STOW97 Advanced Concept Technology Demonstration.
