我刚才说的是 clarifying a point

我刚才说了 As I was saying

我刚才问错了 I just now ask wrong ; I just asked the wrong

我刚才去做午饭了 I just do lunch ; I lunch

我刚才在开会 I meets ; I said in the meeting

我刚才在上课 Me class ; I said in class

就像我刚才说的 Like I said ; As I said just now

我刚才是想下车 I Wanted to Get off

我刚才是 Just be myself
