'태국에서는 무슨 언어로 말합니까' or '태국은 무슨 언어를 구사합니까'

[IchbinderFremde]

They are all fine. (but "언어" or "구사하다" sound formal a bit. I would colloquially say, "태국에서는 무슨 말을 써요?"

Duolingo seems to avoid using the word 말 to mean language, but i found it very common in spoken Korean. 한국말 was a far more common way of referring to the Korean language than 한국어.
