Revolutionary brain-computer interface aids ALS patient
Scientists at UC Davis have created a brain-computer interface (BCI) that helps people who can't talk—like those with ALS—actually speak out loud, just by thinking. Instead of typing out words, this device picks up signals from the brain's speech area and turns them into a voice almost instantly. It's a big step up from older, text-only tools.
How the brain implant works
The BCI uses tiny electrodes in the brain to decode what someone wants to say, then speaks it aloud with barely any delay (we're talking fractions of a second). Users can even learn new words or tweak how their voice sounds for more natural conversations. The team is excited but says more testing is needed before it becomes widely available—they want to make sure it works well for lots of different people.
