Near-monosyllabicity and Voynich: a Bavarian comparison

[Jorge_Stolfi]

This runs into the same problem most solutions do, namely that the set of letters is just too small

Most traditional scripts will use two or more letters to represent one phoneme.  See for example the German use of "oe" for "ö" or "sch" for "ʃ", or English "ch", "sh", "oo", "th", etc.  Thus the "fact" (more precisely, "consensus theory") that the Voynichese script uses fewer letters than most European scripts does not directly imply that the Voynichese  language has fewer phonemes than most European languages. 

and their order too restricted.

But his point is that, if Bavarian is indeed mostly monosyllabic, the order of phonemes in each word (syllable) will be restricted too.  Some consonants can only appear at the start of the syllabe, some only at the end, some only in the middle...

All the best, --stolfi
