Why and how the text could be Bavarian

[oshfdk]

That’s exactly what I wrote earlier: Labels are consonants without vowels, which is why they’re so surprisingly short.

So, when a label appears verbatim as a separate word in the text (and many if not most of them do), how does this work? Initial/final consonants are replaced with vowels? Also, if labels are words without vowels, why is the label length distribution so similar to the word length distribution? Citing Stolfi's work, the word type length distribution of labels and space separated text words is practically the same:

   

Which makes it very unlikely that words in the text and labels are produced in radically different ways, as you suggest.
