Neuralink Telepati reaches 75 words per minute in an ALS patient

What was measured?

Neuralink's Telepati brain-computer interface (BCI) converts the thoughts of ALS patients directly into text and speech. According to the results shared by the company, one participant reached a typing speed of 75 words per minute in the first week of using the device.

The error rate in the same measurement was recorded at 5.8 percent. That means roughly one in every 17 words the system produces needs correction.

Why it matters

ALS (amyotrophic lateral sclerosis) affects motor neurons and can take away speech and hand function. Systems that translate brain signals directly into text offer an alternative to keyboards and voice assistants for these patients.

At 75 words per minute, the system points to a threshold usable for everyday writing; however, it is not yet known how stable the results remain across a larger group of participants and over the long term.

Limits

The data is based on a single participant's first week. Neuralink's results have not been independently verified, and no information was shared about where or how broadly the device can be used.
