- A brain implant can decode internal speech with 74% accuracy when users think of a preset password.
- The device ensures privacy by only activating when a specific keyword is thought of.
- The study, published in Cell, is a significant step towards practical brain-computer interfaces (BCIs).
- BCIs help restore speech in people with paralysis or limited muscle control.
- Internal speech signals are weaker than attempted speech but originate in the same brain region.
- AI models were trained to recognize phonemes and stitch them into words and sentences.
- The device's accuracy is comparable to earlier BCIs designed for attempted speech.
