Stuttering (alalia syllabaris), also known as stammering (alalia literalis or anarthria literalis), is a speech disorder in which the flow of speech is disrupted by involuntary repetitions and prolongations of sounds, syllables, words or phrases, and involuntary silent pauses or blocks during which the person who stutters is unable to produce sounds. The exact etiology of stuttering is unknown; both genetics and neurophysiology are thought to contribute. There are many treatments and speech-language pathology techniques available that may help increase fluency in some people who stutter to the point where an untrained ear cannot perceive stuttering; however, there is essentially no cure for the disorder at present.

People who stutter include British Prime Minister Winston Churchill, orator Demosthenes, King George VI, actor James Earl Jones, US President Joe Biden, and country singer Mel Tillis. Churchill, whose stutter was particularly apparent to 1920s writers, was one of the 30% of people who stutter who have an associated speech disorder—a lisp in his case—and led his nation through World War II. Demosthenes stammered and was inarticulate as a youth, and, through dedicated practice using methods such as placing pebbles in his mouth, became a great orator of Ancient Greece. King George VI hired speech therapist Lionel Logue to enable him to speak more easily to his Empire, and Logue effectively helped him accomplish this goal. This training and its results are the focus of the 2010 film The King's Speech. James Earl Jones has stated he was mute for many years of his youth, and he became an actor noted for the power of his voice. Mel Tillis stutters when talking but not when singing. Many people had their speech impairment only during childhood.

Fictional characters

Some notable fictional characters do stutter.

Literature

  • Bill Denbrough – the main protagonist of Stephen King's 1986 novel It. Bill has a stutter, due to being hit by a car at the age of three, which leads to him being outcast. He outgrows his stutter as an adult; however, it comes back when he learns of It's return and returns to Derry.

Film

Animation

  • Porky Pigcartoon character in the Warner Bros. Looney Tunes and Merrie Melodies series of cartoons. Porky's most distinctive trait is a severe stutter, for which he sometimes compensates by replacing his words; for example, "What's going on?" might become "What's guh-guh-guh-guh—...what's happening?" Porky shared his stutter with the voice actor who originally played him, Joe Dougherty, who was actually a person who stuttered. Because Dougherty could not control his stutter, however, production costs became too high as his recording sessions took hours, and Porky's additional lines were done by Count Cutelli. Mel Blanc replaced Dougherty in 1937. Blanc continued the stutter; however, it was harnessed for a more precise comedic effect (such as stumbling over a simple word only to substitute a longer word without difficulty, or vice versa).
