Replacing Cast sound and soundsets

[Daxtreme]

Hello guys!

I recently opened with Near Infinity the Neverwinter Nights Data files and wanted to change the "lyrics" characters say when casting.

Is it possible to replace the casting vocals in NWN? They bore me, I want the ones in Baldur's Gate 2.

I also want to do the following:

Replace a character's entire soundset for another one, being custom and this being done in single player, inside the campaign?

Any ideas?

Thanks!!!
