Paralyzed Woman Can Now Communicate with AI Brain Implant After Over 20 Years of Silence

A paralyzed woman who couldn't speak for over 20 years can now communicate with AI technology that decodes her brain signals.
She suffered a brain stem stroke at age 30 that left her with locked-in syndrome, able to move only her neck and wink.
New brain implant uses electrodes to read her brain signals as she tries to speak and converts them into a computerized voice.
With this implant, she can "speak" at 80 words per minute, vs only 14 with her old communication device.
She says the implant has given her a sense of purpose and the ability to contribute to society again.
