There are two traditional therapies for adult stutterers.

The first is "stuttering modification therapy." This focuses on reducing fears and anxieties about talking. The stutterer also learns to stop, relax, and move forward with his speech. He still stutters, but it's "easy stuttering," and becomes less important in his life. This can be done with a self-therapy book or with a speech pathologist.

The other therapy is called "fluency shaping." This trains fluent speech motor skills, in other words, the physical skills of fluent speech. It usually begins with extremely slow fluent speech, and then gradually increases the speaking rate until the speech sounds normal. This is usually done in a speech clinic, and often uses speech computers.
