英文....................

Pardon me,can you repaet once more ?
I beg your pardon,can you repeat once more?
Excuse me, can you repeat once more ?

其實多數嘅外國人在通話中突然説
1) Sorry ?
2)Pardon me ?
3)I beg your pardon?
4)Excuse me ?

也可如同「對不起,可不可以重復多一次?」 的意思一樣
(不過要留意這様較為口語化)

Sorry,can you repeat ones?

Sorry, can you speak again?

「對不起,可不可以重復多一次?」
Sorry! Would you mind to repeat again please?
or
Sorry! Could you please repeat again please?

Sorry, can (could) you please repeat that?
or
Sorry, could you please say it again?
