Christmas radio address, he explains to his son the importance of broadcasting to a modern monarchy and demands that Albert train himself, starting with a reading of his father's speech. His attempt to do so is a failure. Later, Albert plays Lionel's recording and hears himself reciting unhesitatingly.
Albert returns to Lionel, where he and his wife both insist that Lionel focus only on physical exercises, not therapy.
Lionel teaches his patient muscle relaxation and breath control but continues to probe gently and persistently at the psychological roots of the stutter. Diagnosing poor co-ordination between Albert's larynx and diaphragm, Lionel prescribed a daily hour of vocal exercises including tongue twisters. Lionel's treatment gave Albert the confidence to relax and avoid stress-induced muscle spasms. As a result, he suffered only the occasional hesitancy in speech. He began speaking confidently and managed his address at the opening of the Old Parliament House in Canberra without
stuttering.
Lionel continued working with Albert through his father’s death and short reign of his brother. During preparations for his coronation, after his brother abdicated the throne, in Westminster Abbey, Albert learns that Lionel has no formal qualifications. When confronted, Lionel explains how he was asked to help shell-shocked Australian soldiers returning from the First World War. Upon Britain's declaration of war with Germany Albert summons Lionel to Buckingham Palace to prepare for his upcoming radio address to Britain and the Empire. Albert and Lionel are left in the broadcasting room to rehearse. He delivers his speech with Lionel conducting him, but by end is speaking freely.
The two remained good friends and worked together for the remainder of Albert’s life. Albert’s stammer continued, but he was able to manage it during important public speeches. If it was not for Lionel’s unorthodox treatment methods, Albert would not have been able to lead the British Empire during the Second World War.
