And indeed Venetian does not have the geminated consonants of Italian, not at all: You are not allowed to view links. Register or Login to view. and You are not allowed to view links. Register or Login to view.

Oh come on. For real?

   

   

Your own example shows double consonants after a few lines already. (Other example of singing italians: quite worthless here)

Doubled consonants can be be found at any corner of venetian, 
so it is just not true to say that there is no „geminizing“ at all in North italian variants. 
At least there are much more than Voynichese can deliver, and maybe less than in today‘s italian.
And this is, again, not the status of some kind of written Venetian 600 years ago.

Simple thing at last: if VMS was in any North Italian variant, someone would have found out meanwhile…

But it isn‘t in Latin or any latin-based language.
