I know you posted this a month ago, but I only just saw it today — sorry! Anyway, here’s my guess at this:
⟨m n ny ng⟩ /m n ɲ ŋ/
⟨p t c ky k ʼ⟩ /p t t͡ʂ c k ʔ/
⟨b d j gy g⟩ /b d d͡ʐ ɟ ɡ/
⟨f s z sy kh gh h⟩ /f s z ʃ x ɣ h/
⟨l r w y⟩ /l r w j/
⟨a e é i o ó u eu⟩ /a ɛ e i ɔ o u ə/

Anyway, here’s my next challenge:
⟨a aa ã ãã b c d đ e ee ẽ ẽẽ g ɣ h j k ꝁ l ł m n ñ ɲ ŋ o oo õ õõ q t v w x y ɏ z⟩
+ ⟨Vˉ Vˍ⟩, which may occur with any vowel.
Sample text:
Ñeeˉcã ɣõˍbaˉ maaˍłõõˉvẽ ɏoˍqee ꝁãˉ.
(I did already post this here, but I’d be interested to see what other phonologies everyone here can think up!)
