Does god speak to me: I am of the opinion that god is and always has been a personal god. Satan is also personal. They each are within. It is our choice to choose which direction we take. So I suppose, in a manner of speaking, both god and satan speak to us all.
Perhaps but only through a dream or vision. (Numb. 12:6) When Einstein was asked if he was an atheist, he answered and said, "Absolutely not! But, I can't think of God relating to man on a personal basis."
Now, Satan is only a concept to illustrate the evil inclination in man. Therefore, an emanation and not a personal being. Metaphorically, yes, God and Satan speak to us all within ourselves.
