The kuài reading of
会 is bound — it appears only inside
会计 (accounting / accountant) and its close derivatives like
会计师 (CPA) and
注册会计师 (certified public accountant). For meetings, ability, or future tense,
会 is always huì. If you see
会 directly followed by
计 in an accounting context, switch to kuài; otherwise default to huì.
