I listened over and over to that sound clip. The oqet is pretty clear; the rest of it I don't think I have completely worked out. In any case, I will agree with Ovaak that the Dothraki 'q' sound is not that bad at all, compared to, say, a Klingon 'Q'.
However, we are stealing Shmosh's introduction thread, so I think we will 'return to our regularly scheduled channel' and continue this thread in the 'beginners' section.
