Acts 2
5-11 Now there were staying in Jerusalem Jews of deep faith from every nation of the world. When they heard this sound a crowd quickly collected and were completely bewildered because each one of them heard these men speaking in his own language. They were absolutely amazed and said in their astonishment, “Listen, surely all these speakers are Galileans? Then how does it happen that every single one of us can hear the particular language he has known from a child? There are Parthians, Medes and Elamites; there are men whose homes are in Mesopotamia, in Judea and Cappadocia, Pontus, Asia, Phrygia, Pamphylia, Egypt, and the parts of Africa near Cyrene, as well as visitors from Rome! There are Jews and proselytes, men from Crete and men from Arabia, yet we can all hear these men speaking of the magnificence of God in our native language.”
Since the Holy Spirit only gives speakers human languages. Examining what is claimed to be a language which turns out is not a language of any kind is a great way to run from the false, human made up false gibberish.
