How Artificial Intelligence gave a Paralyzed Woman her Voice back
At the age of 30, Ann suffered a brainstem stroke that left her severely paralyzed. She lost control of all the muscles in her body and was unable even to breathe. It came on suddenly one afternoon, for reasons that are still mysterious.
For the next five years, Ann went to bed each night afraid she would die in her sleep. It took years of physical therapy before she could move her facial muscles enough to laugh or cry. Still, the muscles that would have allowed her to speak remained immobile.
