Description:

Speak Freely is a application for a variety of Unix workstations that
allows you to talk (actually send voice, not typed characters) over a
network. If your network connection isn't fast enough to support
real-time voice data, various forms of compression may allow you,
assuming your computer is fast enough, to converse nonetheless. To
enable secure communications, encryption with DES, Blowfish, IDEA,
and/or a key file is available. If PGP is installed on the user's
machine, it can be invoked automatically to exchange IDEA session keys
for a given conversation. Speak Freely for Unix is compatible with
Speak Freely for Windows, and users of the two programs can
intercommunicate.
