This AI-Powered Brain Implant Can Turn Your Thoughts Into Speech


for the first time in the history of humanity, scientists managed to capture information directly from the brain cortex using artificial intelligence technology to reconstruct intelligible speech, opening new possibilities of direct brain-to-machine interfaces.

For the moment, scientists are able to identify simple things by analyzing people's brain activity through fMRI scanner. by showing people photos of famous people or objects they relate to, the computer was able to analyze the fMRI data and recognize what they were looking at. The challenge is appealing we cannot use fMRI for daily use cause it's heavy machines that locate only in hospitals, scientists have to create a portable technology that is able to connect to brain cortex and retrieve information.

Last year, neurosurgeon Dr. Ashesh Mehta at the Feinstein Institute for Medical Research on Long Island placed a flat array of electrodes on a patient’s brain, right over the parts of the brain dedicated to speech and hearing. He was also working on creating a system to enable speech on people with a variety of paralyzing conditions, from spinal cord injuries to ALS.

The team working at Columbia University’s Neural Acoustic Processing Lab has been able to solve this challenge by using temporary implants that connect directly to a patient’s cortex too.
According to the researchers, their objective is to create an implant that could be permanent so people that currently use keyboards to talk to others (think the late Stephen Hawking) could synthesize speech on the fly, just by thinking. Like researcher, Nima Mesgarani told New Scientist, “speech is much faster than we type. We want to let people talk to their families again.”
Their implants are now able to capture patients neural signs from the auditory cortex, the signals get transferred to a neural networks algorithm to reconstruct the speech hear a sample of the reconstructed speech.

after training the algorithm on 5 patients connected to the implants, the AI was then able to decode new words - digits from zero to none - and synthesize them. Independent listeners were able to recognize three out of every 4 numbers.

It doesn't seem perfect when u hear it, but it's an opening to what the future would be like since many technological breakthroughs only started with an idea and continued development to a practical solution, the idea still has great potential and it's not hard to imagine near future where people could regain full speech abilities by just thinking what they want to say.
