Godislove, i don't know if God is telling you to do this or not, and i doubt anyone here can tell you for sure. you will just have to seek Him in prayer about it more. i wonder: how do you know that you have arabic or chinese prayer languages?
i can't give you a definite answer, but i have a situation that somewhat relates to yours. i work in a building where my job is to take in bodies to have autopsies done. my job is to take them up in an elevator and make sure they are weighed. i frequently see bodies of children brought in. being a pentecostal believer, i very much believe God can raise the dead and that He does occasionally do it. so i prayed and asked God that if He ever wants me to pray for anyone to be raised up on my job, to speak VERY clearly and distinctly, in such a way that i can't miss it and that there's no confusion about it whatsoever. if i start praying for every body to be raised, i would soon be out of a job (unless they all came back to life.) i don't really have any room for experimentation, you see?
i don't think you'll get in a lot of trouble if you speak in tongues to someone and it doesn't work, you'll just be embarrassed, and you'll learn something about hearing God's voice. but just pray earnestly for the Lord to make this clear and He will, in time, one way or another.
