Brain-computer interfaces tap AI to enable a man with ALS to speak

Recently, researchers have begun developing speech brain-computer interfaces to restore communication for people who cannot speak.

Brain-computer interfaces are a groundbreaking technology that can help paralyzed people regain functions they’ve lost, like moving a hand. These devices record signals from the brain and decipher the user’s intended action, bypassing damaged or degraded nerves that would normally transmit those brain signals to control muscles.
