Sounds like you want back to the stage where you can audibly hear "god" in your mind. When God wants to tell you something directly he usually appears, usually in the guise of this figure described in the bible as The Angel of The Lord, though he has used other methods.
God speaks through his Word the bible, and his actual Word Jesus, whose words are recorded in the bible. If I wanted to hear God's voice I would seek it there.
The quiet voice of the Holy spirit, isn't audible in my experience. Rather he speaks in concepts and unveils meaning of life and scripture.
It's a type of spiritual learning, were suddenly you understand something that hasn't occurred to you before, without the prompting of a physical mentor.
The Holy Spirit works in our lives subtlety and can't usually be seen until we look back and his plan is complete.
One night I had a dream...
I dreamed I was walking along the beach with the Lord, and
Across the sky flashed scenes from my life.
For each scene I noticed two sets of footprints in the sand;
One belonged to me, and the other to the Lord.
When the last scene of my life flashed before us,
I looked back at the footprints in the sand.
I noticed that many times along the path of my life,
There was only one set of footprints.
I also noticed that it happened at the very lowest
and saddest times in my life
This really bothered me, and I questioned the Lord about it.
"Lord, you said that once I decided to follow you,
You would walk with me all the way;
But I have noticed that during the
most troublesome times in my life,
There is only one set of footprints.
I don't understand why in times when I
needed you the most, you should leave me.
The Lord replied, "My precious, precious
child. I love you, and I would never,
never leave you during your times of
trial and suffering.
When you saw only one set of footprints,
It was then that I carried you.
