Two-Way, Freeform, Speech-to-Speech Translation Systems for Tactical Use

The Spoken Language Communication and Translation System for Tactical Use (TRANSTAC) is developing and fielding freeform, two-way translation systems that enable speakers of different languages to communicate with one another in real-world tactical situations without an interpreter. To date, several prototype systems have been developed for traffic control points, facilities inspection, civil affairs, medical screening, and combined operations domains in Iraqi Arabic (IA), Mandarin, Farsi, Pashto, Dari, and Thai. Systems have been demonstrated on various-size platforms ranging from personal digital assistants (PDAs) to laptop-grade platforms.
