2023名校版高考英语阅读理解精读含答案 An artificial intelligence can decode（解码）words and sentences from brain activity with surprising—though still limited—accuracy. Using only a few seconds of brain activity data, the AI guesses what a person has heard. It lists the correct answer in its top 10 possibilities up to 73 percent of the time, researchers found in a study. Developed at the parent company of Facebook, Meta, the AI could eventually be used to help thousands of people around the world unable to communicate through speech,typing or gestures, researchers report August 25 at arXiv.org. Most existing technologies to help such patients communicate require risky brain surgeries to implant electrodes. This new approach“could provide a practical path to help patients without the use of invasive methods,” says neuroscience Jeean-Remi King, a Meta AI researcher in Paris. King and his colleagues trained a computational tool to detect words and sentences on 56,000 hours of speech recordings from 53 languages. "The tool, also known as a language model, learned how to recognize specific features of language. With the help of a computational method, the team tried to decode what participants had heard using just three seconds of brain activity data from each person. The team instructed the AI to match the speech sounds from the story recordings to patterns of brain activity that the AI computed as corresponding to what people were hearing. It then made predictions about what the person might have been hearing during that short time,given more than 1,000 possibilities. The correct answer was in the,AI's top 10 guesses up to 73 percent of the time, the researchers found. The new study is “decoding of speech perception, not production,”King notes. Though speech production is the ultimate goal,for now,“we’re quite a long way away.” 32. What is the main idea of paragraph1? A.The principle of human brain activity. B.The limitation of human brain activity. C. The definition of the artificial int
