Which plaintext languages to try?

The best ones I know are the plays/monologues by You are not allowed to view links. Register or Login to view. from ~1500, like You are not allowed to view links. Register or Login to view.. 

PS. You may want to use the "edizion moderna" which uses a more phonetic spelling.  The original spelling seems to use the Italian spelling for many words, with doubled consonants, which which I suppose were not pronounced as such.

  Original: ... de arivare a l’herba nuova, cavalla magra, e imbozzia, a me reffare pure ...
  Modern:  ... d’arivare a l’erba nuova cavala magra e imbolsía. A me refaré pure ...

The latter is much more like what "my" Venetian would sound like.

As for the dialogues collected/created by Francesco Artico, they are in modern Venetian from the Piana, the region just east of Venice.  That is only 2'500'000 cm from Treviso, and that dialect sounds very much like "my" Venetian. (One difference I noticed is that he says "pìe"= "feet" with stress on the "i", whereas in "my" dialect it is "piè" with stress on the "e".)

All the best, --jorge
