I am very sorry for you, that appear to be saying you can’t hear the Voice of God
I first heard the voice of G_d in Tupelo, Mississippi in 1929. I was walking down the street, eating a tuna fish sandwich.
The “sheep that hear His voice” is talking about responding to the Gospel, responding to the voice of the Good Shepherd who calls us to His salvation.
Hearing God’s voice does not mean you hear the actual voice of God on a daily basis and receive daily messages from Him. Now, it can happen that God DOES give you a specific message from Him, but you better understand that that means you fall under His test of prophet as given in Deuteronomy.
God has given us His message in His Word, the Bible - it is from His Word that we “hear” his voice - not from some daily special revelation. I’m not saying God cannot give a prophetic message - He can do anything He wants, but that probably will be the exception, not the rule.
We can daily “hear” His voice through His teaching and His guidance given in His Word - that’s pretty miraculous in and of itself - don’t you think?
