User blog comment:OtterJiang/Thai VOCALOID Might Not Be the Best Idea/@comment-53539-20150115095222

Considering a number of other languages sound like you're trying to throw up as you speak... There is a language in Africa which has click sounds as spoken sounds... Basically... If there is a sound the human throat can make, I'm sure its in a language *somewhere* in the world. And with the roughness of the software taken into account as well, I'm going to say that not all the potential Vocaloid has will be pretty.
