You heard voices from and in your mind. The voice of the Spirit will come from the inner man, and He will speak with the voice of God. He will speak the words of God. He will confess Jesus Christ as Lord. Every other way of understanding the bible will lead to deception, and loss of some part of life from Jesus.
He was clear, His sheep hear His voice. They know Him and follow Him.
In your example above, neither voice was the Spirit's voice.
When you hear His voice, you will know. If you believe in Him, you have heard His voice, when He convicted you that you were dead in your sin, and needed saved, needed His cross for your forgiveness of sins, needed His resurrection for your new life as a child of God, needed His miracle of the Spirit giving you new birth.
He told you of these things, He chose you to hear Him.
