Alright so as the subject says what can mimic voices perfectly?

Here’s the story:

My wife and I have been hearing one another’s voice when the other isn’t nearby at all and when we hear the others voice our dogs immediately get scared and start whining. I have heard the voice which sounds like it’s outside saying my name and also our dogs name. When I hear it all of the hair on my body immediately stands up. My wife has heard what sounds like our son crying but when she checks on him he isn’t crying, she has thought she has heard me talking but I’m not talking at all. When she takes our dog out at night she hears something running and thinks it’s our dog but the dog comes from the other direction. For geographical reference we are in the mountains of Western North Carolina. We are not near a Indian reservation but used to be Cherokee land. Also there were slaves on this land. We are not in isolated woods either.

Can anybody identify what this could be?
