RFK Jr.’s Strained Voice: What is it?

If you’ve ever tuned into Robert F. Kennedy Jr.’s speeches, you’ve likely noticed his unique, raspy voice. What some may not know is that it’s not just a quirk—it’s the result of a rare neurological condition called spasmodic dysphonia, which Kennedy has battled for decades.

“I have a tremble in my voice, especially when I first start talking,” Kennedy explained in a 2004 interview on The Diane Rehm Show. Rehm, who herself suffers from the condition, was among the first to identify the symptoms in Kennedy’s speech.

Kennedy admits that early in his career, he received numerous letters from listeners who speculated that he had spasmodic dysphonia, urging him to seek help. It wasn’t until later that he was officially diagnosed with the disorder.

Spasmodic dysphonia is a neurological disorder that causes involuntary spasms in the muscles controlling the vocal cords. These spasms result in a voice that sounds strained, quivery, or breathy.

According to Dysphonia International, this condition affects approximately 50,000 people in North America, with women being more commonly affected than men. The cause of spasmodic dysphonia remains unknown, and there’s no cure.

While there’s no cure for spasmodic dysphonia, there are treatments to manage its symptoms. One of the most common treatments is botulinum toxin injections, often referred to as Botox, which are administered directly into the vocal cords. Kennedy himself has used Botox injections for years to help control his voice. “I get shots about every four months,” he told The Diane Rehm Show in 2005.

Despite the treatment, Kennedy has admitted that he still can’t stand the sound of his voice. “I feel sorry for people who have to hear it,” he told The Los Angeles Times in 2024. “My voice doesn’t get tired, it just sounds terrible.”

Kennedy has also shared that the more he uses his voice, the stronger it tends to get—though the sound remains difficult for him to tolerate. “If I could sound better, I would,” he remarked, adding that he simply can’t help it.

Kennedy, who is vying for the role of U.S. Secretary of Health and Human Services under President Trump, is no stranger to the public eye. His upcoming appearance before the Senate Finance Committee on Wednesday marks the beginning of hearings to confirm his nomination.

For many, his struggle with spasmodic dysphonia is just another layer to his complex public persona. It’s a reminder of the personal challenges he’s faced while fighting for causes he believes in, from environmental protection to public health.

Kennedy’s story underscores the resilience it takes to overcome a condition like spasmodic dysphonia while continuing to pursue high-profile goals. And even though his voice may not sound “perfect,” his message remains clear: determination runs in the Kennedy family.

As the hearings unfold, Kennedy will no doubt face scrutiny for his policies and his voice alike. But as always, his fight for what he believes in shows no signs of wavering.
