Conference on BSD, and another situation

First I’ll start with the other situation. I want some type of unix software,
that opens a file (that is text), and outputs it with some type of text-to-speech engine to a .wav file, and have asterisk call this.

Second problem:
I am on FreeBSD, so meetme won’t work, so I am told.
I also had trouble getting app_conference to compile.
Any other way to do a voice bridge, or to get those two working?
