I have many friends in China and Japan who have huge trouble learning english.
I tried to do a little experimenting to find some language that we could all learn easily (since we are all huge language nerds) and I stumbeled across esperanto. Esperantos grammar is extremely simple, but its pronounciation system is not exactly universal. Sure it is easy for the speakers of european languages, but it really does not help in this situation. Immediately I thought of creating my own conlang that would have a truly universal and easy pronounciation, but I just wanted to know if somebody already had invented a solution. Thank you
