You are very close to my previous plan. I studied linguistics in university, and I generally studied science, so the curriculum is mostly language and literature, which is far from the interdisciplinary subject you mentioned. The two disciplines you mentioned will have majors in graduate schools. Undergraduate students majoring in computer science in general language colleges take computational linguistics (for postgraduate entrance examination, the specialized course is computer knowledge, not linguistics, and some colleges take both), so I suggest you enroll in computer science or other adjacent disciplines.
