The old voice did not have all the files necessary, as a significant number of words had been introduced.

We will be producing different voice packs although initially this will be focused on different languages.

The voice used will depend on availability. If we have to make substantial changes in the future, and the voice actor is not available, then we have to rerecord all of the words. Otherwise it is too jarring to have some of the words in one voice, and others not.

Even if you could access the old voice, ~40% of the voice files would have to be the new voice as there was no recording for it in the old voice.
