I can't comment accurately on how I'd pronounce dwarven words because it's not something that I have put a lot of thought into... but I can make some insights on how I think a dwarven mind and personality works.
Basically I thinks dwarves are totally unhinged.
Seriously, the amount of emotional pain that things that happen to them seems to cause is related entirely to how long ago it happened to them. Losing their beloved and having to drink the same old booze both sting the dwarven psyche equally painfully, and something as simple as being able to check out a really cool looking lever is enough to assuage being forced to breathe in the rotten reek of their decaying wife. They also deal with unhappiness and joy in absolutes. 'Once I feel THIS unhappy, I will go berserk and start throwing all the levers until I feel better, and not a moment before.'
Dwarves also universally enjoy inflicting pain upon their enemies. Any dwarf in the military (that I have seen, I could be wrong) will take great joy in slaughter no matter what it is they are told to kill. A goblin, wildlife, the dwarven caravan merchants, they will kill any targets with unrestrained glee.
They're also obsessive to the point of insanity. barring being possessed, when a dwarf has a strange mood he comes up with this idea that they absolutely MUST realize, RIGHT NOW; they'll happily toss whoever is in the craftshop they want and bring your goblet production to a screeching halt because they need to make a flute covered in spikes and pictures of cheese. If they can't scratch that mental itch, they lose their sanity, either going berserk, insensate and demented, or simply so depressed they choose to starve to death.
TL; DR: Dwarves are nuts.
