大声谈论的英文

We are dicussing loudly when teacher come in.或者We are talking aloud when teacher come in.

老师和你都不一定是错的，这要看语境了，语境当中是不是真的要翻译“大声讲话”，还是只需要“交流”这个意思就行。如果非要翻译“大声讲话”可以使speakout,speakloudly,talkloudly,speakup.其实都是“讲出来”，“说出来，让人听见，讲大声”的意思

We were talking aloud when our teacher came in.While we were talking aloud, the teacher came in.

不知道你说的“大声讲话”是用于什么场景，我说两个可能合适你用的场景：说大声点：speak louder!大声说出来：say it loud!望采纳！
