A system that records the brain's electrical activity through the scalp can turn thoughts into words with help from a large language model – but the results are far from perfect

Using only a sensor-filled helmet combined with artificial intelligence, a team of scientists has announced they can turn a person’s thoughts into written words.
In the study, participants read passages of text while wearing a cap that recorded electrical brain activity through their scalp. These electroencephalogram (EEG) recordings were then converted into text using an AI model called DeWave.
Chin-Teng Lin at the University of Technology Sydney (UTS), Australia, says the technology is non-invasive, relatively inexpensive and easily transportable.
