A way back to conversation.
A man with ALS used an experimental brain–computer interface to turn attempted speech into conversation.
- AI’s role
- Neural decoders translated recorded cortical activity into words, then synthesized speech.
- Documented result
- The study reported 97.5% word accuracy after further training, sustained over 8.4 months.
- Important limitation
- One participant, implanted electrodes, and specialist support. This is not a broadly available treatment.
