The Deep End

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.
