A natural way to say: can you speak more slowly please?
大家好!
If I'm talking to a Chinese friend, how should I say this:
"Can you speak more slowly, please?"
Some things I found on the internet:
1) 请你慢一点说?
2) 请说慢点
3) 请说慢一点
4) 请慢点
5) 你可以慢慢说吗?
6) 你可以说慢一点吗?
7) 你可以说得慢一点吗?
Could you please explain the differences between them (context, meaning) and recommend a natural/native/authentic way of saying that to a young friend?
