How to pronounce Vilja?

Since I've been toying with the idea of also playing Oblivion now that I can get it for such low cost I was looking at possible mods and this question came to mind because its the first mod I downloaded, just in case I get the game going.

I know Vilja means Willpower but I'm not sure how it is supposed to be pronounced! I guess the pronounciation can depend on the language, I can think of several ways:

For the first syllable 'Vil' it could be similar to the French Ville or perhaps more of an E sound like Veal? My guess is it sounds like Ville but I could easily be wrong.

And for the second syllable Ja it could be one of several ways:

Vil`ya (my first guess)
Vil`ha (my second guess)
Vil`ja (my third guess)

I'm not sure how the "ja" might be prounced but I'm assuming its a Swedish variation of some kind so maybe it is `ja with the J sound after all

I've always thought of its as sounding like "Ville"+"Ya" but "Veal"+"Ha" has a distinctive European ring to it also

Please enlighten me, or maybe you could even run a contest on this, see how knowledgeable people are of names
