The idea of a mind-reading machine might freak a lot of people out, but a new device that can transform brain activity into speech could be the first step towards a lifeline for patients who have lost the use of their voice.

Finding ways to translate our thoughts into machine-readable signals is a booming area of research as our ability to record brain waves steadily improves and machine learning approaches making the decoding process ever easier.

One of the most compelling use cases is helping those who have lost their voices due to injury or disease speak again. For a long time, the best we’ve been able to do on this front is the kind of device used by renowned physicist Stephen Hawking, where the user selects letters or words from a screen using movements of whatever muscles they can still control at just a few words per minute.
