It's more than possible to add more words to the V364/magic Voice. We "merely" need to implement the PARCOR filter encoding. I experimented with this earlier using the SPTK (http://sp-tk.sourceforge.net/). Note that the V364/magic Voice ROMs contain the PARCOR filter coefficients in a (yet undeciphered) compressed format but it's still perfectly possible to feed the T6721A using uncompressed data since that is how the real stuff works as well (decompressing on the fly). I still have all the uncompressed data dumps in case someone is interested, as I actually used those to reverse engineer the PARCOR speech synthesis of the T6721A. Many years ago I sent some of them, along with the bit format to Stefan Uhlmann and he hosted it on his very informative website. Alas, it is no longer online, but as always, archive.org comes to the rescue:

In an ideal case, phonemes could be synthesized using the PARCOR synthesis and those very condensed phonemes could be used to implement any kind of speech. It would probably occupy a lot less memory than the usual, old fashioned stuff (SAM etc.).
