Silent Talk
(U) Silent Talk will allow user-to-user communication on the battlefield without the use of vocalized speech
through analysis of neural signals. The brain generates word-specific signals prior to sending electrical
impulses to the vocal cords. These signals of “intended speech” will be analyzed and translated into
distinct words, allowing covert person-to-person communication. This program has three major goals: a)
to attempt to identify electroencephalography patterns unique to individual words, b) ensure that those
patterns are generalizable across users in order to prevent extensive device training, and c) construct a
fieldable pre-prototype that would decode the signal and transmit over a limited range.
