Spirituality: Do people hear God's voice? Speak in Tongues?

Some people claim to hear God talking to them. Some claim God is speaking through them, as in some people might speak in tongues. It is because of their own personal weaknesses of needing attention do people speak in tongues. God does not speak. Only humans speak. Also, one may have a weak mind and possibly psychotic disorders such as schizophrenia. Remember, you cannot touch, see, hear, smell, or eat God. You can only realize it. Anyone that claims they can is not right in their mind.
