What's next for the human voice?

Scientists are going to extraordinary lengths to help people speak again. What's next for Jules, and what's next for the rest of us as we search for connection in a world with texts, AI and synthetic voices?

Your voice can now be cloned — and used without you. The same AI that can give a voice back to someone who has lost it can also separate a voice from the person it belongs to. What does this division mean in our modern era?

Casey thinks of a sentence. A computer says it out loud, in a voice that sounds like his. Brain implants are beginning to turn thoughts into speech, bringing scientists closer to something that once seemed impossible.

Jules lost his voice. Then AI gave it back. Voice-cloning technology can now recreate voices for people who can no longer speak — raising a remarkable possibility: How much of a person can a synthetic voice restore?

Jules is losing his ability to talk. Now he faces a decision that could silence his natural voice for good. A voice carries more than words — emotion, identity, even a smile. As Jules weighs his choice, we explore what makes a voice so personal, and why letting it go can be so difficult.

Jules Rodriguez has always had a lot to say — as a dad, podcaster and stand-up comedian. As ALS takes away his ability to speak, we discover why voices are so deeply tied to who we are and what it’s like to face losing your own.

What if you lost your voice? Today, AI can recreate it, and brain implants can turn your thoughts into speech. This season of The Deep End: Talk to Me follows the people living through these vocal transformations — and asks what these remarkable technologies can teach us about why our voices matter at all.

Jon Nelson shares how he’s doing these days, now that his depression is gone. 

Several years after surgery, Jon and others have found relief. Here’s a look at what’s next for them and what’s next for deep brain stimulation research.

Jon details the intense stigma, shame and judgement that comes with depression and its treatments. Is there something different about changing our brains versus other body parts?
