Researchers successfully reconstructed sound from just human brain activity

WHY THIS MATTERS IN BRIEF

What is the thoughts in your head weren’t so secret after all?

For the very first time Artificial Intelligence (AI) has been used to scan and decode brainwave patterns and then turn those patterns into audible sounds – that are freakily recognisable as you can hear from the video below. And it now means that we can now, literally, listen to the thoughts inside your head.

Combine this with the ability to stream the imagery associated with those thoughts in your head and play them as a video on the TV, as we’ve also already done, and suddenly you might just realise that sci-fi is dead. And you might now also be realising that even the thoughts in your head in the future aren’t safe – and you’d be right especially as the tech to “at a distance is now also developing at a fast rate.

 

See how it’s done

 

In their ground breaking study the team successfully reconstructed what they call the “perceptual experiences from human brain activity and provide insights into the neural representations of sensory experiences.” Or, what I said above.

Historically reconstructing these arbitrary sounds from the human brain has been avoided because of the complexity of the temporal sequences in those sounds and the limited resolution of neuroimaging technologies like fMRI.

However, while we’ve seen numerous developments recently in Generative Artificial Intelligence (GAI) systems that can take different inputs such as text and turn them into music and assorted sounds this is the first study where the researchers used it to reconstruct sounds from decoded brain waves. And it’s scarily impressive as I think you’ll agree.
