what is wrong with robert f kennedys voice

Robert F. Kennedy Jr.s voice has been described as raspy and strained, and he has been public about being diagnosed with spasmodic dysphonia, a specific form of an involuntary movement disorder called dystonia that affects only the voice box. This rare neurological disorder causes voice breaks during speaking and can make the voice sound strained. Kennedys condition began as a mild tremble for a couple of years and gradually worsened over the years. There is no cure for the condition, but patients can undergo speech therapy or counseling. Kennedy has explained that his voice is the result of an injury that caused spasmodic dysphonia, and he cannot listen to his own voice. However, he has also stated that his voice has been improving and getting stronger.
