跟 我 说 = gēn wǒ shuō

"能不能别学我说话“

We need to be careful about the nuances of different languages here. 1. repeat after me This means "Say again what I have just said in the way I said it in order to learn it". It is a conscious instruction. In Chinese, it is "我每说一句，你照样跟着说一句，把这个学会。" This applies to singing as well. The verb is 唱. Replace 说 with 唱. 2. He just repeats what I say, like a parrot. 他像鹦鹉学舌， 我说什么，他就说什么。 3."Stop repeating everything I say." 别学我说话。 This is not neutral at all, just as the English original is not neutral. The English original is quite rude and peremptory (unless when you are playing with a close friend or a lover).

If you are a little child 学我是小狗！ IS OK！ If you are older 别学我说话 IS OK

不要重复我的话
