"Don’t you mind me speaking English? & Don’t you mind I speak English?" Both of your sentences are grammatically incorrect. The correct way to say them is: Do you mind my speaking English? Do you mind if I speak English? The meaning is the same. If you say, "Don't you mind..." you are conveying an expectation that the person should mind something. For example: Don't you wear a swimsuit at the beach? (You are surprised that the person doesn't wear a swimsuit at the beach because it's contrary to your expectation.) Don't you mind John's singing in the car? (You should mind because his singing is awful.)

Lynn is NOT CORRECT. First, This sentence is grammatically incorrect: "Don't you mind I speak English?" Second, adding the word, "about" in the sentence changes the meaning and is not what Danyel asked.

Lynn is correct. Please follow her advice.

This is an interesting question. As a question you can either ask: Do you mind if I speak in English? -or- Would you mind if I speak in English? Both questions are essentially the same question with the difference being the initial question word (do/would) Asking with 'would' is more polite, but using 'do' is not rude or wrong, just not as polite. If you are using it in a statement, then you can use the negative form (don't) Please don't mind if I speak in English - this is technically a correct sentence, but not used. It's more so insinuating that you are a nuisance because you are speaking in English. You could say "I don't mind speaking in English" or "I don't mind speaking English" if someone is switching to your language but you are comfortable speaking in English or if someone is trying to communicate with you through google translate apps. But for your question about what the differences are: "Don't you mind me speaking about English?" you are using the word "about" this means that you don't want to speak in the language of English you just want to talk about the language of English in an educational fashion OR about English people from England. "Don't you mind I speak English?" this insinuates that you want to communicate in the English language. I hope this helps and clarifies!

Actually both are incorrect. More appropriate one would be - “please don’t mind if I speak in English”.
