FAS Project on Intelligence Reform

SPEAK EASY

RADC developed and certified SPEAK EASY, a secure voice, digital communications system for use over standard telephone lines. The Center began work on the system in 1975. SPEAK EASY's high data-rate performance was consistent with encryption devices of the period. Initially tested and evaluated in March 1981, the 16 kilobit/second modem/VINSON Secure Voice Terminal was transitioned to ESD in June 1981 -- whereupon it became known as "SPEAK EASY."
