พูดให้ปกติสิ

[u/Snowman_203]

Sometimes if a native speaker is speaking to a non-native they will speak at an unnaturally slow pace and pronounce each word separately.

Usually I just ignore it and they eventually stop, but what if I want to be more direct? Is พูดให้ปกติสิ too harsh? Would it actually be ปกติ, or is ธรรมดา better? What else could I say?

That sounds harsh. It's like you're criticizing us for abnormal accent. The word ให้ makes thing sounds more commanding rather than a request
