I was reading
this TCRF page as well as
this thread, and it had me thinking about a few things that I wanted to bring up here:
It's likely well known by now that hlminhal and hlmexhal have been found in Duke Nukem Total Meltdown's sound data. They were used for the airtank likely when it had the goggles (before V0.99), and it would've likely interchanged between the two sounds for as long as Duke had the item activated. It could've also been for the spacesuit.

Comparing the technical parameters of those, as well as practically every Duke (himself) sound's technical parameters, plus the obvious hint here with it being included in "Duke Movement Sounds", we can infer that this is an unused Duke line:

definesound DUKE_YES yes.voc 0 0 255 4 0
Perhaps this was a nod towards ROTT, as one of the character's says "Yes!" when certain things take place in the game. Since there's a few others like DUKE_PASSWIND, DUKE_GLAD, DUKE_HEHE, and DUKE_SHUCK, we can assume these are also unused Duke lines, but these are not defined, only labeled, so I can't compare the bit parameters. PASSWIND is obviously meant to be a fart or a reaction to such a thing. No idea what the others could be, but my guess is HEHE and SHUCK could've been taunts, while GLAD may have been a line used for something specific to a level or use of an item. There's another sound that has a definition but is missing the sound file:

definesound GENERIC_AMBIENCE22 vpiss2.voc 0 0 255 4 0
The parameters are the same as the other GENERIC_AMBIENCE sounds that are Duke lines (as well as most of his other sounds). So this is likely also another cut line.
If vpiss2.voc is an unused Duke sound, then that would mean there are 8 cut Duke related sounds that are mentioned in the CON files, and they existed in V0.99 and onward. If we include the 2 sounds that were removed after V0.99 (think06.voc and seen01.voc), that would be 10 cut Duke sounds, 11 if you count the sound from the beta's RTS file that was replaced with Duke's scream in the final release.
With all that considered, and not including audio that exists in the GRP but is unreferenced/unused, I'd guess there's likely around 12-15 lines total that may have been cut from the game, but only 11 of them do we have any leftovers of. As I said, DUKE_BREATHING/DUKE_EXHALING have been found, and of course the beta contains 3 lines that were not found in later versions, but as for the rest - I don't think there's any sound files around for those. Maybe a few made their way into DNTM and DNZH, but I'm unsure.
