From Neal's review way back when:

With the Command version of Aces, you have: control of your deck gun; access to the Med (slipping past the British at Gibraltar is tough!); you can obtain a Type XXI elecro-boat, available upon promotion; and voice recognition. Supposedly you can set the program and issue most orders verbally. It's a nice thought but I couldn't get it to work reliably. As things began to get critical, my "Crash Dive!!" and "Set Course 3...4...6!" orders were met with a quizzical "What's that, Herr Kapitan?" Usually the game would end right there by ramming or my wife demanding I stop waking the baby with all my shouting. Thankfully you don't need to know German to swim.

I remember reading that the sound in CAOD is actually worse, with the engine sounds not always working properly, but I could easily be misremembering that. I do own both, but my play (as with most other u-boat sims) always runs out about mid-1940, so I really can't say with any kind of accuracy what all the differences are.
