是这样的—— 正确读音：kou3 jue2 （只适用于考试和新闻播报。） 正常读音：kou3 jiao3（生活中都是这么说的。如果用那个正确读音会产生需要解释一下的效果。）

本来我觉得肯定是ke jiao，但是查了字典之后发现！卧槽！指争吵的时候居然真的ke jue！不过我相信绝大部分中国人都会念成kejiao。so 以后字典可能需要修改了。。 Thanks a lot～ You are my Chinese teacher：）

Haha, you are really scrupulous. Both of them are correct, but KouJue is in literature and in ancient Chinese. Kou Jiao is more common in nowadays, and I suggest you use Kou Jiao, otherwise, people may think it is a little strange and think you are a nerd.

In Taiwan, we pronounce it as Kǒujiǎo’

口语里，作“争吵”用的时候，听到的“kǒujiǎo”多于“kǒujué”
