As I see it this can be:
1) God actually speaks (in their chosen language) as a voice in their head.
2) They see some spectacle of natural magnificence (such as a sunset or a rare wild bird) and interprets this as a form of communication from God.
3) They experience a feeling of elation or happiness and interpret this as some message from God.
In cases 2 & 3 is there not a more justifiable explanation than the voice of God?
Are there any other conduits for the voice of God?
So the question here is: What do people mean when they say that God "talks" to them?
