1 Scientists have created a new tool that can turn people？？s thoughts into words. It works by using an AI program to translate brain activity into words. The sci? entists say the program could help people who can？？t speak because of a brain injury.

2 The new method involves two main parts. The first is a scanner that allowed the scientists to record brain activity. The second is an AI system that the researchers trained to turn videos of brain activity into words.

3 To record brain activity without surgery， the scientists used a big machine called an fMRI machine. The machine uses strong magnetic （有磁性的） fields and radio waves to create pictures showing which parts of the brain are active. It can record the activity of the brain as it happens.

4 To translate these recordings into words， the researchers used an AI tool called GPT?1， which predicts which word is most likely to come next， based on the information that came before.

5 The scientists first trained GPT?1 on lots of stories people had told about their lives. Next， the researchers trained GPT?1 to make connections between brain scans and spoken words. The testing was done on three human volunteers. Each person spent sixteen hours inan fMRI machine listening to stories. The people imagined the stories as they heard them， and the fMRI machine recorded their brain activity. GPT ?1 then used these recordings of brain activity to make connections between the words and ideas in the stories and the brain activity of the listeners.

6 Then came the test： The researchers played a new story. GPT ?1 was only given re? cordings of the people？？s brain activity. But the words that GPT?1 predicted were very simi? lar to the words in the story that the people were listening to. For example， when a person was listening to a story about a person who didn？？t have a driver？？s license， the program came up with this，“She has not even started to learn to drive yet.”

7 GPT ?1 is the first AI program to turn what people are thinking into words without brain surgery， but it cannot be easily used today， mainly because of the size and cost of fMRI machines.
