Just use a microphone to grab voice from Xbox speakers :)

I cannot, because I have the german version of both games.
But you can download the demos and extract them yourself.

You just need a program called: "Universal Extractor", which is able
to extract all files from almost all installers.

With the help of Universal Extractor and Game Extractor, I was able to extract voice files from the Call of Duty 1 and 2 Demos. I still need to figure out how to extract sounds from Splinter Cell: Chaos Theory and converting them to wav format.

I will check that...wait...

Update:// I'm sorry, but SCCT uses modified/nonstandard Unreal-Tournament files. None of my tools could unpack them...

I found and corrected an error in Hotel's SWD file - the kissing woman has her Actor reference "Tetka" replaced with "Tetk1" from MotMod 1.01. This is because Actor reference "Tetka" uses American voice files.

By the way, is it possible to make new sound files register in the ai.shadvs file? I had a close look at the file. hykao claimed that the French workers in White Head don't say anything. Well, actually they do - try bashing one of them up and you'll notice that they use British voice clips. Also, apart from some scripted dialogue in Renegades if you make a boat fall on top of Shestakov, male Soviet peasants don't say anything. Although there's a folder called "panic_ded", it is never used - and all of the voice files in it are slower versions of what's in the Russian "panic" folder.

Yes. I've created a new actor (Tetk1) with english voice template.
About this woman, she can't speak while kissing :)

Why not? I can't say exactly because I do nothing with voice files. Maybe AHO know more about it.

Well with DtS all of my work modifying this file were not successful.
With MoT, I don't know, perhaps there are other ways to implement
voices/sound (=> Scripting).

So, has anyone tried to add new stuff to the "male_rus_ded" voice template yet?

Update on my addon for MoTMod:

All MoT missions except Shefferd now have "Attention" music from DtS. Apparently, adding "Attention" music in Shefferd affects the script when blowing up Tsavalov's room, causing the game to crash.

By the way, what kind of MoT features can be expected in Jagdpanther besides the Heil Hitler salutes? And is it possible to access SCM files? These are used for the cutscenes in MoT missions.

Besides of new objects/textures and Heil Hitler trigger, I'm planning to add yellow status for soldiers and level zones.
BTW, Wehrmacht military salute will be used instead of Heil Hitler.

Of course it's possible, but I don't know how :)
As I see, these files are very small and uses fixed size (62 bytes). Maybe later I'll try to analyze them, but for now I've focused on SWD.
