Unlocking Speech Through Brain Implant & Machine Learning

[gleem]

TL;DR Summary

An experimental system connecting electrodes implanted in a brain can display words that a person thinks of saying.

In a collaboration of several institutions researchers have been able to record the thoughts of a person with a brain stem stroke resulting in anarthria (an inability to articulate speech) by mplanting network of electrodes in the brain and using a machine learning algorithm to decode the thoughts of words and display them on a computer screen.

RESULTS​

We decoded sentences from the participant’s cortical activity in real time at a median rate of 15.2 words per minute, with a median word error rate of 25.6%. In post hoc analyses, we detected 98% of the attempts by the participant to produce individual words, and we classified words with 47.1% accuracy using cortical signals that were stable throughout the 81-week study period.That's about the state of my typing skills.
