The 52-year-old actor, who won an Academy Award for playing stuttering British monarch King George VI in the 2010 drama "The King's Speech", is putting the experience to good use by supporting the Action for Stammering Children organisation, reported Contactmusic.
British politician Ed Balls announced Firth's appointment at an event in London, saying, "He has agreed to become a vice president of Action for Stammering Children, to help us with the next phase of work and keep raising the profile of the charity and change the perception of stammering."
