Was Voynichese meant to be pronounced?

[Common_Man]

Just logically speaking, I don't expect someone from 1400s to sit and write a 200 page manuscript and make it non pronounceable, or a full on obscure text (unless it's of utmost importance, as in a military/spy/religious document?). Come on.. What are the odds that one encrypts something into a non pronounceable form and when needed someone has to sit and rewrite the whole thing (at once/page by page for reading) which will roughly take another 200 pages or so of vellum, ink, effort,etc?
