What is the diversity of tongues given by the Holy Ghost?

In the book of Acts and some of the epistles, the writers of the Bible describe a miraculous speaking in foreign languages, or "speaking in tongues." In the book of Acts, those so enabled by the Holy Spirit fluently spoke languages they had never learned or studied, in order to preach about Jesus to people who spoke another language, to praise God, or to prophesy. In his first letter to the Corinthians, the Apostle Paul says "if I speak in the languages of men and of angels, but do not have love, I am only a resounding gong or a clanging cymbal." Because of this, some Christians believe that the gift of tongues also enables people to speak the languages of angels, whereas other Christians believe that Paul is using hyperbole, and that the gift of tongues only applied to human languages.
