東北弁 Pronunciation Question about Ch's


I've been trying to learn Tohokuben and I have a question.

I'm interested in Tohokuben and recently found this website
<https://konnok3.sakura.ne.jp/dialect.html>. I know pronunciation can vary all
over the Northeast but I've heard that きゃきゅきょ is often pronounced ちゃちゅち. But
I've also heard that つぁつぉつぇare possible. Is is that きゃきゅきょ = ちゃちゅち but ちゃちゅち =
つぁつつぉ

E.g.

客 = ちゃく but 着 = つぁく

or should both of these groups be pronounced the same? If so, when or where is
each used?

E.g.

客 and 着 = ちゃく in some areas but 客 and 着 = つぁく in others?
