USA NSA Voice Data SAVILLE ← VINSON
Advanced Narrowband Digital Voice Terminal
ANDVT, or Advanced Narrowband Digital Voice Terminal, is a family of devices
for secure voice communication via narrowband channels,
developed in the late 1970s by the
US National Security Agency (NSA)
for use by the US Department of Defense.
ANDVT uses LPC-10 voice compression (vocoder) and the secret
SAVILLE encryption algorithm
jointly developed by GCHQ
and NSA.
Some ANDVT devices were backward compatible with the earlier
VINSON wideband voice encryptors.

An interesting open-source project for an ANDVT-like solution that you
can build yourself, can be found on GitHub. User aarmono demonstrates
how he uses two Raspberry Pi 3 units to send an encrypted message over
narrowband shortwave radio.
