A way to “Detect Speech” from People’s brain

We don’t just make any old ran­dom noise when we talk; we’re think­ing about our words, and that makes us able to speak fluently.

Meta’s new AI can scan a person’s brain­waves to “hear” what some­one else is say­ing to them. In oth­er words, it can tell which words you hear by read­ing your brain­waves. This is not the first time this con­cept has got­ten spot­light. In 2019, Amer­i­can sci­en­tists had devel­oped an arti­fi­cial intel­li­gence that could accu­rate­ly read brain sig­nals and trans­late them into speech.

Talk­ing about the Meta’s recent AI, it can decode speech from non­in­va­sive record­ings of brain activ­i­ty. Neu­ro­sci­en­tists have always dreamt of decod­ing speech from some­one’s brain for a long time, but inva­sive meth­ods were need­ed to achieve this.

The spe­cial­ty of the new tech­nique, accord­ing to the researchers, is that it is non-inva­sive, which means that researchers do not have to implant like… elec­trodes, in anyone’s brain.

Non­in­va­sive tech­niques such as elec­troen­cephalo­grams, EEG, and mag­ne­toen­cephalog­ra­phy, MEG, can scan the brain from the out­side and watch activ­i­ty with­out any surgery, but the prob­lem is that they are too noisy.

In order to address this prob­lem, researchers turned to machine learn­ing algo­rithms to help “clean up” the noise. They used the mod­el wave2vec 2.0.

Brain-wave-read­ing AIs seem to be an excit­ing new tech­nol­o­gy that can be used to help peo­ple with speech prob­lems, like peo­ple who can’t speak, and those who have had strokes or oth­er issues that cause speech difficulties.

But so far, only lab-based research has been done on brain­wave-read­ing AI. They haven’t been avail­able for use in the real world yet.

The future of Neural AI technologies 

The future of AIs is will not be lim­it­ed to be act­ing as a cure for peo­ple with speech prob­lems. With advance­ments in tech­nol­o­gy, it’s not far­fetched to think that advanced form of AI could be used as ways for com­put­ers to com­mu­ni­cate with each other. 

As seen by sci­en­tists and AI researchers, brain com­mu­ni­ca­tion will help humans work bet­ter togeth­er with arti­fi­cial intel­li­gence and machines. The day is com­ing, some say it has already.

Potential Misuses?

When we think about the future of tech­nolo­gies like Meta’s Brain-wave-read­ing AIs, we should­n’t for­get about the poten­tial for mis­use, should we?

In the future, will these kinds of hacks also be pos­si­ble against our brains? Could crim­i­nals hack into our minds to get infor­ma­tion from us?

Well, we do have trou­ble with peo­ple who spread false news sto­ries on social media to stir up anger. But still, that’s too much for assumption.

In fact, it’s too child­ish to stop the progress of some­thing new just because it has some poten­tial for mis­use. Let’s keep in mind that peo­ple can also use every sin­gle piece of tech­nol­o­gy for evil pur­pos­es, and they still do it.

Meta’s new steps are look­ing promis­ing, and we are in the cor­rect path among few, at least, till now.
