Neuralink has taken a historic step in the human trial process. The company’s first participant, Bradford G. Smith, who has ALS, prepared a video using only brain signals and published it on YouTube. Smith, who had lost the ability to speak, showed through this video that he could both speak again with his AI-supported voice and control devices with the power of thought.

Neuralink’s ALS patient created a video using brain signals

The approximately 10-minute video was produced entirely with brain-computer interface (BCI) technology. Smith details the transformation he experienced in the video. Smith, who could previously communicate only with an eye-tracking system in low light, says that he can now easily use his computer even outdoors in daylight.

Stating that his child attended the award ceremony and can communicate independently, Smith once again demonstrated the freedom provided by technology with the statement, “I am writing and editing this video with my brain.”

Another innovation that stands out in the video is Smith speaking with his voice synthesized by AI. Neuralink says that this voice is generated from the individual’s past voice data and is controlled solely by brain signals.

The footage shows Smith moving the cursor and interacting with different applications step by step. This system will pave the way for individuals who cannot speak or have severe physical disabilities to exist independently in digital environments.

Neuralink recently launched a worldwide patient application process for two separate projects called PRIME and CONVOY. The company’s goal is to increase the number of users who can access this technology to over 1,000 by the end of 2026.
