Sorry for this mini necromancy, but I finally found a good extractor/player to hear the sound/dialogue files in the .ITA file. Maybe it can help extracting the .INT files, too.

The program is called Ravioli Explorer, part of Ravioli Game Tools, if you're interested.

When you open the program and search for the folder containing the sound files, put "All files" and look at any .INT file you want to explore/extract: it will list all the sound files (.wwise) contained in that file.
