The 'Chinese' Theory: For and Against

[ololololo]

In this theory, the idea (I believe) is that voynichese glyphs could represent a variety of things, including -but not limited to- consonants, vowels and tones

It seems to me that the author simply recorded the sounds without dividing them into consonants or vowels, and indicated the tones at the end. In that case, the transcription would be similar to Latin.
In general, I think that Voynichese glyphs and bigrams are tied to hieroglyphs rather than phonetic units, which may explain words like chedaiin (which may be a two-hieroglyph word). So, some simple sounds like jiu, juo, etc. should have been used as a basis.
We also can't say whether the author wanted to make Chinese more understandable for us. Perhaps his only goal was to convey Chinese phonetics in the most accurate and beautiful way possible, without considering any Latin alphabet.
