Robert F. Kennedy Jr.s voice has been a topic of discussion due to its distinct raspy and strained vocal tone. Kennedy has been public about being diagnosed with spasmodic dysphonia, a rare neurological voice disorder that affects the voice box or larynx causing the vocal cords to spasm. Kennedys voice began to change in the late 1990s, and he has undergone surgery and alternative therapies to improve his voice. Despite his voice condition, Kennedy remains firm that his voice wont be a roadblock in his presidential aspirations.
