I have all kinds of videos on WWII, but footage with audio of these generals is rare. I've never heard Rommel speak either. Given all of the film shot during the war, you'd think more footage with sound would be available.

Interesting the things you find on youtube. 
"Your knees almost go weak, at the tremble of Scott's voice as Patton."
Scott sounded like everyone wished the real Patton sounded. In actuality, the real George Patton had a rather high pitched, squeaky type of voice. He sounded nothing at all like you anticipated he'd sound. There's not a lot of footage with him speaking, but the footage I have seen is so different from what you'd expect.
True, I saw a few historic reals and his voice was much higher than Scott's. I like Scott's Scrooge also for the gravely voice.
Eisenhower, Patton, Montgomery all had voices of higher pitch. I never heard Rommel's, Marshall's was a lower voice, be interesting to see what other Generals of that era spoke like.
