Firth is a clear favourite to claim Oscars gold on Sunday (27Feb11) for his portrayal of the king in the film - and officials at the American Institute for Stuttering feel the honour will be well deserved.
Director Chamonix Sikora tells WENN, "The King's Speech is a magnificent film, and it has had an enormous and important impact on our cause because it shows that anyone can have a stuttering disorder - even a king.
"We congratulate Colin for his Golden Globe and Screen Actors Guild awards, and we wish him the best of luck at the Oscars."
Sikora claims more than three million Americans and 60 million people worldwide suffer from stuttering-related impediments.
She adds, "Stuttering is extremely complex and often misunderstood, but help is available for anyone at any age. Whether it's early intervention for a young child or equipping someone to tackle a stressful job interview, we've been fortunate to help people gain lasting freedom from the disability of stuttering. It's a life-changing experience, both for the client and the clinician."
