A man with ALS has regained the ability to use fluent everyday speech via a brain-computer interface implant. The technology translates brain activity into voice in real time, allowing the user to communicate independently at home. This system has enabled the patient to maintain a full-time job.
What changed
New data confirms a 47-year-old patient is using a BrainGate clinical trial implant to work and speak for up to 12 hours at a time.

Brain-Computer Interface Restores Fluent Speech to Man With ALS
confidence 90%A man with ALS has regained the ability to use fluent everyday speech via a brain-computer interface implant. The technology translates brain activity into voice in real time, allowing the user to communicate independently at home. This system has enabled the patient to maintain a full-time job.
What's confirmed:
- A man with ALS has restored fluent everyday speech using a brain-computer interface implant from the BrainGate clinical trial.
- The interface translates brain signals into speech with up to 97% accuracy.
- A 47-year-old man with ALS used the device to communicate independently at home and keep a full-time job.
- UC Davis researchers developed a brain-computer interface that translates brain activity into voice instantaneously.
Still unconfirmed:
- Casey Harrell can now talk for twelve hours at a stretch.
- The number of people with electrodes in their brains has more than doubled in the last couple of years.
- Paradromics has implanted its first brain-chip in a human patient to restore communication.
