The best word to describe Vietnamese is gurgling, but not the pleasant river-like gurgling -more like the kind of a sound you'd hear a frog make before choking on its own saliva. The language also has an annoying, whining tone to it, and that makes it sound like the people speaking it would be constantly complaining. Vietnamese speakers tend to spit a lot while speaking too, and that's really not a miracle considering all the frog-like croaks they have to produce all day long. Vietnamese is a lot worse than Finnish or Korean or the other languages rated higher on this list - just try sitting in a bus full of gurgling and whining Vietnamese speakers, and see if you come back sane.M+7
I wonder why nobody hasn't voted for this language that makes extremely nasal sound. I tried so hard since there are so many Vietnamese around me but you know, a guy speaking in Vietnamese is the worst, in my personal opinion. I don't know about any structures or grammars of Vietnamese, so no offense about it. But the sound really is killing me.M+16
I live with Vietnamese people and they seem incapable of having a normal, calm conversation. Even saying "I love you" or "Can you take the trash out" will sound like they are fighting. It makes me want to rip either my ears or their vocal cords out.M+6
You people are wrong Vietnamese is beautiful like Spanish!
