Yes, it's all alright. But, i am very busy within these days. Maybe, next week i can finish it, it's ok!
Some extra point of view, the /ә/ sound represents the "mid central vowel" (also known as schwa) according to IPA in Banlamgi; however, the /ә/ sound that represents the /æ/ sound (near-open front unrounded vowel, or near-low front unrounded vowel) in Azerbaijani language. So, they have the same kind symbol, but they are different from the sound representation. That is, the Banlamgi to the /ә/ sound maybe it's more closed to IPA.--Andrei Ꞓuà (thó-lūn) 2021-nî 7-goe̍h 19-ji̍t (Pài 1) 18:51 (UTC)
