In 2025, doctors placed a tiny device on top of a person's brain, and it read their thoughts and turned them into spoken words through a computer, letting someone who could not talk speak again.
A brain-computer interface is a special device that reads signals from inside the brain and turns them into something useful, like words. In 2025, doctors placed one on a person's brain, and it picked up brain signals when the person tried to speak, so a computer turned them into spoken words, giving them a voice again.
A see-saw and a jump rope are just playground toys that do not read brain signals or help anyone communicate.
Scientists keep making these devices better, and one day they might help many more people who have trouble speaking share their thoughts.
