Brad Smith, a 63-year-old father of three from Arizona, has become the first person with amyotrophic lateral sclerosis (ALS) to regain his voice using Neuralink’s brain-computer interface (BCI) implant. This achievement marks a significant advancement in assistive technology for individuals with severe motor neuron diseases.
A New Era of Communication
Smith, who has lost the ability to move or speak due to ALS, received the Neuralink implant in his motor cortex. This device allows him to control a computer cursor by imagining specific movements, such as tongue motions or jaw clenching. By focusing on these imagined actions, the implant interprets his neural signals, enabling him to navigate and interact with his MacBook Pro. New York Post
Restoring a Personal Voice
To narrate a video he edited, Smith utilized an AI-generated voice clone created from recordings of his speech before ALS affected his vocal abilities. This synthetic voice provides a more personal and authentic communication experience, allowing Smith to express himself in a manner reminiscent of his pre-ALS days.
Enhanced Independence
Prior to the implant, Smith relied on eye-tracking technology for communication, which was limited to specific lighting conditions and environments. The Neuralink implant has expanded his ability to communicate in various settings, including outdoors. He has even used the technology to play video games like “Mario Kart” with his children, highlighting the device’s impact on his daily life and family interactions.
Technical Aspects of the Implant
The Neuralink device, approximately the size of five stacked U.S. quarters, contains over 1,000 electrodes and is implanted using a robotic system designed to avoid blood vessels, minimizing surgical risks. The implant connects wirelessly to external devices, translating neural activity into actionable commands without the need for physical movement.
Broader Implications
Neuralink’s success with Smith has garnered attention from the medical community and regulatory bodies. The U.S. Food and Drug Administration (FDA) recently granted the company’s speech restoration device a “breakthrough” designation, aiming to expedite the development and availability of such innovative treatments for patients with severe speech impairments.

Conclusion
Brad Smith’s experience with Neuralink’s brain chip and AI-generated voice underscores the potential of emerging technologies to transform the lives of individuals with debilitating conditions like ALS. As research and development continue, such advancements offer hope for enhanced communication and independence for many facing similar challenges.
