You can hear the real Patton’s voice here:

It’s slightly higher in pitch with just a bit of an aristocratic air (Patton was personally quite wealthy) absent in the gruff George C. Scott portrayal.
That's a cool speech, I've never seen it. Patton himself hated his voice but his voice is higher than mine and whenever I call someone it's always OK Ma'am, can I put you on hold? I don't bother correcting them now and it's always a woman that does it. His also doesn't sound 'Californian', more mid west but he grew up in Southern Ca.
Patton also practiced his War Face all the time to get that hard ass look he had.
Patton had a lot of money and was also resented for that.
