Depends where live presently. Im filipino and grew up with Salvadorans so I picked up the Salvadoran Dialect. What the first poster said is true. Just learn the basics and you can change it here and there depending what dialect you want to use.

I also speak it with a slight american accent as Im ameican and speak English for the majority of my time.

You will also start to pick up the accent of the spanish speakers you are most exposed to.
