Story summary

Stanford researchers created a brain-computer interface (BCI) that converts imagined speech into text for individuals with severe paralysis.
The system decodes neural activity from implanted microelectrodes, achieving 74% accuracy with a 125,000-word vocabulary.
Privacy is protected through a password system to prevent unauthorized access.
Future enhancements focus on improving accuracy and minimizing unintended speech interpretation.
