reading vs. hearing and watching

Hearing a speech is very different from reading one, but how do they affect someone's perspective towards a specific subject? As I was reading the Patton's speech that he gave to his troops, it felt like I was not quite comprehending the message. I can pin-point the skills he applied to his speech like the repetition, the obscene language, specifying to one particular audience, and the form of unity such as Americans and the word "We". This helped me understand the rhetoric part to an extent but it did not help me fully comprehend how it would have affected the troops. Patton's words on paper seemed motivational, but I didn't get the feeling as if I was actually there as one of his soldiers. He does use rhetoric in the straight foward sense, making his message clear as to what he was trying to persuade his troops to do. Words can be very effective. They carry a value of either lesser or greater importance that are taken into account when listening to a speech.
On the other hand, when I was watching the speech that Patton gave in the film, by just hearing his raspy yet strong tone of voice, it made me want to go out and fight in the war. The close up on his face was eye catching, his emotion could easily be read and his passion to win the war was written all over his face! Just hearing the speech out loud, with the exact tone that a general would use is persuasive enough to get the troops pumped up. The length of his speech was shorter which in this case worked for the film and the actor himself. He properly gave his speech with few words but with a lot of motivation and inspiration to get an army going. In conclusion, comparing the film versus the written speech really made a big difference as to what Patton was trying to get out to not only the troops, but America itself!
