I don't know that I've ever met a Christian that hears Jesus' voice. One reason is that very few in his presence in his day heard his voice, many did for a little while and then they turned away. It's not clear that more than 10 or 20 ever did. In his day.
But in his day his voice was available, not in christianity. Paul has a voice, John has a voice, Revelations has a voice, the apostles have voices, not jesus. He's been reduced to a non-speaking part, maybe one or two lines.
In jesianity, Jesus religion, he has all the speaking parts. Call no one your teacher, he said except me. Jesus.
