Yeah, this is a superb movie, deserving of all its Oscars. Especially Firth.

Rating: Null/10 (27 April 2011)

What does "speech" refer to in the title? By definition it can be "something spoken", as the speech to the nation near the end of the movie. Or it can be "the ability to express thoughts through sound".
I suppose the title refers to the going-to-war speech that King George delivers by radio, but I enjoyed it more for the other definition, the process by which the King's speech (manner of speaking) was improved by the rogue Logue. Rogue because he had no degree, no formal certification as a doctor of speech therapy, but a keen mind and experience that enabled him to turn the king from a hopeless stammerer to a king that gave inspirational speeches.
Colin Firth won the best actor Oscar for his role as King George VI. It is difficult now to imagine any other actor doing it as well. Superb performance.
Geoffrey Rush was nominated for best supporting actor for his role as Australian Lionel Logue. The movie and its script were derived from diaries that Logue had kept and that were discovered by Logue's grandson in 2001.
Helena Bonham Carter is effective as Queen Elizabeth. As is Guy Pearce as the older brother King Edward VIII, who quickly abdicated because he was in love with a twice divorced woman from Baltimore and could not gain the support of the British subjects.
Something I rarely do, I read the Logue book of the same title several weeks before I saw the movie, on DVD. The book focuses more on Logue himself, his early life in Australia, and what caused him to stay in London. The book also dwells more on Logue's importance, and the sticky fact that through all of this Logue never became wealthy, as if he had been the main reason the monarchy succeeded but received only a pittance in return.
Good movie, everyone ought to see it, not only for the subject and the performances, but for the historical significance of the period leading into World War 2.
