Quote #1
BERTIE: My physicians say it's good for stuttering, relaxes the throat.
Bertie tends to smoke when he gets nervous about speaking because his physicians have told him that it relaxes his throat. This was actually a common medical opinion in the 30s, but Lionel Logue has no trouble seeing that the physicians are idiots.
Quote #2
BERTIE: Because I bloody well stammer!
When he first meets Logue, Bertie is understandably short-tempered. After all, he is the most powerful man in the world and he can barely say a word to this mere common man.
Quote #3
LOGUE: Do you stutter when you think?
Logue's first order of business is to convince Bertie that his stuttering is a psychological problem and not a physiological one. He makes this first point by reminding Bertie that there's no stuttering when Bertie thinks or mutters to himself. That means there's something wrong with his ability to speak to other people.
