On October 28, Neuralink published a blog post disclosing the early feasibility study of its speech restoration project VOICE. The blog post revealed that an ALS participant reached an output speed of 75 words per minute in the first week of use, with a word error rate of 5.8% on a large vocabulary of 125,000 words. The study's principal investigator, Dr. Nader Pouratian, has presented the relevant data at the 2026 NEALS annual meeting. The study plans to enroll approximately 6 participants who have lost the ability to communicate due to ALS, spinal cord injury, or stroke, with the primary endpoint being device- or procedure-related adverse events within 12 months after implantation. Neuralink has not yet published a complete peer-reviewed paper; the above figures come from a single participant, and the company has not explained the types of test tasks, the separate performance of text versus speech output, or long-term effects.
