Was Voynichese meant to be pronounced?

[MarcoP]

Thank you, Koen, interesting suggestion! 
I removed spaces, transforming each whole line into a single word. It does not seem to make much difference. Italian has significant word-boundary effects, avoiding the occurrence of vowel-vowel at word boundary. Word-boundary effects are also frequent in Currier B.

These are the vowels detected on the "no spaces" files:
Dante:  a e i o u
CUVA_A: A I N
CUVA_B: A
EVA_A: a o
EVA_B: a o

So it seems that my guess that the problems with Voynichese are due to word-end / word-start preferences was not grounded.

PS: in the plots for Dante, deleting spaces moves 'u' from the extreme left to the right of the PC1 vowel range. This could indeed suggest that the special position of 'u' in the original file is due to the fact that it rarely appears at word end (while all other vowels are common in that position). But, as this experiment shows, the method is complex enough to make "intuition" very misleading...
