Unfortunately, I'm looking for the answer to that question myself. I'd love to say "Adjutant", but there hasn't been an update in a long time and I presume the author(s) don't have adding Sound extraction support for
Halo 2 very high on their priorities list regarding tool updates.
Best advice I can give you is two different tools, both of 'em with drawbacks (Namely, no Batch Extraction, at least as far as I was able to deduce).
ADI is one such. It should get you the scripted dialogue easily from the H2X .map files, but it'll only get you one out of numerous audio files in a single .snd tag file (Ex. Battle Rifle shots), if it can access them to begin with. Here's a download link (I tested & scanned it with AVG beforehand; no red flags):
http://ibotmodz.net/forum/files/go/a9f2e83523af10ddbf02ef390e98d31a/adi, or another link for a "v.2.0.1" (Presumably the newest version, but no idea if it was updated 'officially'):
http://www.h2mt.org/repository/tools.phpThe other is Gravemind for H2V. The latest version is 1.6b (You
may need 1.5 for the plugins, according to this link: http://www.modacity.net/forums/showthread.php?22274-Gravemind-1.6B). I think I fetched mine from here:
http://www.h2mt.org/repository/tools.phpI've got 1.6b on my hands, but my experience has not been smooth (Could be user error, but I didn't hear promising reports from others). The tool has long been out of date and I believe has trouble running on 64bit or post Windows XP systems (Don't take my word for it, it's just vague recollection). When I've managed to find a user route that avoids the tool crashing and successfully performed an extraction, I've had errors such as stretched length (And pitch with it).
It would be lovely to have tools on hand for a much more up-to-date & smooth user experience getting
Halo 2's audio, but I don't see much interest surrounding the game itself for it's assets (It's unsatisfactory PC port, and that may be too kind a word for it, doesn't help matters). Pity, 'cause that NPC dialogue holds a place in my heart more special than the rest of the franchise.
