I think that some Christians are mystical and think they are hearing God when they are mentally ill, or hearing spirits or voices from within, usually medications will relieve this phenomenon. There are some so-called "prophets" who are "in touch" with God in a special way, and to hear from God and can speak "prophetic utterances"; however, this is rare and not the norm.
The normative way for God to speak is through His Word. "In these last days He has spoken to us through His Son" (cf. Hebrews 1:2). Let us not be skeptics, though, and find ourselves opposing God. Even the Pharisees who opposed the apostles said that may be a spirit or an angel had spoken to Paul. Hearing God's voice doesn't necessarily mean superiority, but possibly being a prophet, as David heard God's voice audibly on occasion, but relied on Nathan the prophet. Soli Deo Gloria!
