There are several language translators available in Second Life ... my preferred one is the "Universal Translator" from Hank Ramos.
It translates 35 languages ... including some Asian, the translations are done in the text chat window.
You just choose your own language from the drop down blue menu that you get when you click on the box ... it will then translate the text chat from others who have also clicked on the box ... from their language to yours ... amazing.
What is even more amazing is that it is free. There are several scattered around Int.Schs.Island, including in the Mod.Foreign Languages area on the 5th Floor in the Curriculum Tower. You can pick up your own translator at http://slurl.com/secondlife/Grignano/100/97/28
