why does rfk jr sound like that

Robert F. Kennedy Jr.'s distinctive and often gravelly voice is caused by a rare neurological condition called spasmodic dysphonia. This disorder leads to involuntary spasms in the muscles that control the vocal cords, causing breaks, strain, a shaky or strangled quality in his voice. The condition is neurological, meaning the brain sends abnormal signals to the muscles controlling speech, and it has affected him since his early 40s. Despite the challenges it causes, the voice does not get tired but sounds terrible due to these spasms. Treatments like botulinum toxin injections are sometimes used, but the condition is chronic and without a cure. Kennedy has openly expressed discomfort with how his voice sounds but continues to speak publicly despite the impairment.
