Hello Stuttering CEO You have it right that stuttering is a neurological problem and often heridtary. Many stutteres are fluent alone but stutter with their peers. For most of us speech therapy is useless and even harmful. Stuttering (bad speech) is similar to bad vision or bad hearing which is a physical defect that is often ameliorated by a prosthetic such as eyeglasses or Hearing aids. Similarly stuttering is often helped by a prosthetic such as the Edinburgh Masker or DAF (Delayed Auditory Feedback).
