. His distinctive raspy and shaky voice is caused by a rare neurological disorder called spasmodic dysphonia. This condition involves involuntary spasms in the muscles that control the vocal cords, leading to a strained, shaky, or breathy voice. Kennedy was diagnosed with spasmodic dysphonia around the age of 42, and it has affected his voice ever since. The disorder does not impair other vocal functions like laughing or shouting but causes a noticeable tremor or strain in speaking. He has managed the condition with treatments such as botulinum toxin (Botox) injections, which help relax the vocal cords
