Well, on a simple level you might say: You: So, how will this restructuring of the company affect me? Your boss: I'll talk to you about it this afternoon. Talk to = one-sided, will give instruction. Or: You: I am worried about how this restructuring of the company will affect me. Your boss: I will talk with you this afternoon. Talk with = a discussion, two-sided. HOWEVER, the two can be used interchangeably; if somebody says they will talk to you, they probably do not mean that only they will talk and that you will not get to say anything at all. In short, you can use either.

That depends on the context of what you are trying to convey. Technically they are both correct. "Talk to someone", implies you are telling that individual something. "Talk with someone", implies that you will have a conversation with them. The majority of native English speakers, at least Americans, use both phrases interchangeably. I would personally use, "Talk with someone", but that is my own opinion. Good luck with your English progression~

I think both of them are correct
