Brain implant translates thoughts to speech in an instant

A brain-reading implant has allowed a woman with paralysis to hear what she intends to say nearly instantly. Enhanced with AI algorithms, her brain–computer interface (BCI) can simultaneously decode words from neural signals and turn them into speech within 3 seconds. But there’s still room for improvement. Although the BCI works for short sentences, it still operates with “quite a big delay” compared with a natural conversation.
