Terry was diagnosed with bulbar-onset amyotrophic lateral sclerosis (ALS) in 2024. While he is still able to move his mouth and body, his speech has become impaired to the point where his loved ones have difficulty understanding him.

Through the VOICE trial, Terry is using his Neuralink implant to help fine-tune a brain-to-voice interface for himself and others who can’t speak. He trained the algorithm first by miming speech as best he could, then by simply thinking the words and hearing them come out in his own natural voice.
