And I'm sure other people have noticed for quite a while, but when you greet a biped NPC there is often a voice clip of 'hello', and it seems to be randomized a bit.
It just seems weird that when I greet something like a Ssilsk or Saris they sound human. Kind of illusion-shattering.
At the same time it's probably far too minor to be changed right away, but it's just kind of weird.
