Experimental Brain Chip Allows Man to Speak Again Through AI

Terry Mandable, who lost the ability to speak due to Amyotrophic Lateral Sclerosis (ALS), has been able to communicate again with the help of an experimental brain chip developed by Neuralink. The device, implanted in the speech motor region of his brain, detects neural activity associated with attempted speech and uses artificial intelligence to decode these signals into text and audible speech.

In a particularly emotional moment, Mandable was able to convey three words to his wife, Lori: "I love you." The words appeared on a screen and were spoken aloud, astonishing Lori. "You're thinking the words? And they're popping up?" she marveled.

Before his diagnosis, Mandable was an outgoing professional who had recently achieved partner status at his company. However, ALS gradually impacted his speech, leading to difficulties in both professional and personal communication. He was eventually placed on long-term disability and retired from his career.

Mandable became the third participant in Neuralink's experimental Voice study, which aims to develop a brain-computer interface capable of interpreting intended speech from neural signals. The system works by capturing thousands of channels of neural activity and training a decoder to translate these signals into language.

Researchers instructed Mandable to attempt to say sentences, even if the sounds were not understandable to those around him. The system focused on the brain signals and intention behind his attempts. As the technology learned the patterns, it began to produce recognizable language, with one demonstration resulting in the computer stating, "Hello, how are you doing today?"

"Getting back to normal life, is what having Neuralink is all about," Mandable said. His wife expressed the profound impact of the technology, stating that regaining the ability to simply have a conversation means "the world to us."

The Neuralink device is still experimental and has not yet received FDA approval for general use. Further research is required before such technology could become widely available. For Mandable, however, the study has already restored a vital part of his life and identity.
