There are quite a lot samples which likely aren't used in the game. The keelhaul-description is in there, too (which is a dialog option, but Guybrush refuses to say this). And a whole bunch of different prices for Monkey Island, including XBOX points, while the game only seems to use the original "59.95 + tax" one. Many lines include alternative takes, which the game seems to ignore as well.
I guess, any sample not referred in speech.info is not used.
