Unfortunately AT&T decided to keep the information on the *format* for
digital data storage for the Voice Power board, proprietary.   The information
on the DSP that is on the VP board is also proprietary, although the new
models (DSP32 family) aren't.   The internals about on-the-board compression
are hidden away as trade secrets within AT&T, probably never to be released.

Things like text-to-speech (and how to create your own tts libraries),
silence compression, and speech recognition were never fully supported
on the UNIX pc (although this might be different with the 6386WGS VP product).
The VP Reference Manual states that those components of Voice Power are
for "evaluation" purposes only.

The VP board can do rudimentary voice recognition.  I have a small program
that will recognize "yes, no, one, two, three, and four" but that's it.
I have *no* idea on how to add to the recognition models to add new words,
and of course no one at AT&T has been of any great help in that department.
