The human problem

ALS can leave thoughts intact while taking away the ability to speak clearly.

Communication depended on limited movement and other people interpreting speech.

Neural decoders translated recorded cortical activity into words, then synthesized speech.

The study reported 97.5% word accuracy after further training, sustained over 8.4 months.

For one participant, the system supported self-paced conversations.

One participant, implanted electrodes, and specialist support. This is not a broadly available treatment.

Test reliability, safety, and usefulness with more participants and longer follow-up.
