Yesterday I spent a couple of hours deactivating mods in groups of 5-10 and starting Skyrim everytime, so I located 3 mods that were the cause of the language mixture (soul gems, weapons and armos fixes, sounds of skyrim), for the 2nd one there is an ITA localization for a previous version that doesn't work too well so I turned it off for now, as well as the others. For sounds of skyrim there's an ITA version of the wilds, I'll try it. Thank you. Gabriele
