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.

What this video demonstrates—and what it does not establish

What this video demonstrates

  • Transition from mimed speech training to silent speech-intent decoding in a participant with bulbar ALS.
  • Integration of personalized voice-cloning synthesis (noted in the official description as powered by Grok Voice) with neural decoding.

Scope limits & what it does not establish

  • Short highlight clip; see the companion full video `_j806JHhCRo` for the training progression and clinical context.

How this fits into Neuralink's broader clinical and hardware roadmap

This video sits inside the Speech restoration (VOICE) research track on StonkBuilder's independent Neuralink hub. All Neuralink hardware (the N1 implant and R1 surgical robot) and clinical programs (PRIME NCT06429735, CONVOY, and VOICE NCT07224256) remain investigational and have not received FDA commercial marketing authorization.
