where the author clearly didn't worry about the actual pronunciation or orthography, and trying to come to with a phonological framework where the spelling and pronunciation would make sense in something resembling a plausible language
Why the fuck are the apostrophes there when they don't seem to affect the pronunciation? what's with the doubled letters? i think it's meant to be said like "John Jones" but why does the <o> have two different sounds?
So here's my wild speculation: the apostrophe marks affrication. <j> without the apostrophe represents a palatal stop /ɟ/ but with the apostrophe it becomes more or less english /dʒ/.
Doubled consonants immediately following a vowel indicate the "short" version of a vowel. The double <zz> indicates an English-like /z/ sound, rather than the /ts/ the letter represents in some languages
kinda like "gyoan gyoants"
