That is a really good question!
There is only one way I know that God is speaking to me: that is, if I am reading the Holy Bible. That is the only way God has spoken to us since the Apostle John wrote the end of the book of Revelation.
If you want to HEAR God out loud with your ears, read it aloud, or if you can, listen to an audio recording on any one of many apps of the Bible.
This is not a flippant answer on my part. I gained this after many long years of suffering because of people who claimed I should be able to somehow take the thoughts in my head and attribute them to God.
