Researchers have developed a mind-reading brain implant that decodes "inner speech" —a person's silent thoughts—into text or audio, enabling patients with paralysis or motor neuron disease to communicate more easily than with previous methods that required attempted vocalization.

These sources discuss the advancement of brain-computer interface (BCI) technology designed to restore communication for individuals with speech impairments.

A significant innovation highlighted is the implementation of a password protection system, which ensures the BCI only decodes intended thoughts, addressing crucial privacy concerns. This development marks a substantial step toward creating more accurate, reliable, and user-controlled speech-enabling devices, with future improvements focused on enhancing hardware and exploring additional brain regions for even higher fidelity.
