- Scientists at Stanford of USA have developed a brain-computer interface (BCI) that activates only when users think of a preset password.
- The BCI decodes internal speech—sentences users imagine into text or audio using AI models trained on brain signals.
- It focuses on signals from the motor cortex, where both spoken and imagined speech originate, though internal speech produces weaker signals.
- The system interpreted 74% of imagined sentences correctly and recognized the thought-password “Chitty-Chitty-Bang-Bang” with 98% accuracy.
