Tankar blir tal med dator?

Med låga frekvenser kan hjärnan hypnotiseras och bearbeta ej hörbart ljud.

Forskare har skapat ett system som tolkar hörsel och tankar vilket kan omsättas till datoriserat artificiellt tal, genom att övervaka vågor i hjärnan och avläsa dem.

Detta kan leda till nya områden för de sjuka som imte kan tala men som oftast har den mesta forskningen militär bakgrund. Att avläsa tankar är ytterst prakiskt för de som kontrollerar vårt samhälle, både sina medborgares tankar samt främmande medborgare. Tänker vi ett steg löngre är det inte bara möjligt att avläsa dem utan även sönda dem. Den som tar emot dem har ytterst svårt att urskilja sina egna från inplanterade. Detta ör givetvis redan utvecklat och testat i flera decennier men har av naturliga  skäl inte avslöjats. Hue skulle medborgare reagera om de visste att regeringar och andra ”hemliga makter” spionerade på dem och styrde deras liv?  

Att hypnotisera människor är dessutom möjligt utan deras vetskap. Signalen läggs in i vilken media som helst, på TV , mobil, dator, reklam , Youtube klipp eller dylikt. Ofast mycket låg då hjärnan uppfattar men inte fullt hörbar. Vågen når hjärnan öndå med sitt budskap som adresserar det undermedvetna. På det viset kan folk ”få ideer ur det blå” , tex att Gud ör väldigt stor och alla ”otrogna”ska dö.  Tekniken kallas ibland för Voice to skull ” Röst till skalle” . 

Dolda RF signaler togs patent på redan på 70-talet som bilden visar. Dr Duncan är en av utvecklarna för detta och beskriver det som ”Touchless Torture” vilket videon med samma namn finns att se.

Nedan är artikeln på eneglska. Elon Musk och google har redan apparater för detta de presenterat på Ted Talk;

I’m about to announce a ‘Neuralink’ product that connects your brain to computers ” Jag ska släppa en produkt som kopplar din hjärnan till datorer”

  • Elon Musk says he will soon announce a Neuralink product that can make anyone superhuman by connecting their brains to a computer.
  • He says Neuralink increases the data rate between the brain and computers and will give humans a better shot at competing with AI.

In a scientific first, Columbia neuroengineers have created a system that translates thought into intelligible, recognizable speech. By monitoring someone’s brain activity, the technology can reconstruct the words a person hears with unprecedented clarity. This breakthrough, which harnesses the power of speech synthesizers and artificial intelligence, could lead to new ways for computers to communicate directly with the brain. It also lays the groundwork for helping people who cannot speak, such as those living with as amyotrophic lateral sclerosis (ALS) or recovering from stroke, regain their ability to communicate with the outside world.

These findings were published today in Scientific Reports.

”Our voices help connect us to our friends, family and the world around us, which is why losing the power of one’s voice due to injury or disease is so devastating,” said Nima Mesgarani, PhD, the paper’s senior author and a principal investigator at Columbia University’s Mortimer B. Zuckerman Mind Brain Behavior Institute. ”With today’s study, we have a potential way to restore that power. We’ve shown that, with the right technology, these people’s thoughts could be decoded and understood by any listener.”

Decades of research has shown that when people speak — or even imagine speaking — telltale patterns of activity appear in their brain. Distinct (but recognizable) pattern of signals also emerge when we listen to someone speak, or imagine listening. Experts, trying to record and decode these patterns, see a future in which thoughts need not remain hidden inside the brain — but instead could be translated into verbal speech at will.

But accomplishing this feat has proven challenging. Early efforts to decode brain signals by Dr. Mesgarani and others focused on simple computer models that analyzed spectrograms, which are visual representations of sound frequencies.

But because this approach has failed to produce anything resembling intelligible speech, Dr. Mesgarani’s team turned instead to a vocoder, a computer algorithm that can synthesize speech after being trained on recordings of people talking.

”This is the same technology used by Amazon Echo and Apple Siri to give verbal responses to our questions,” said Dr. Mesgarani, who is also an associate professor of electrical engineering at Columbia’s Fu Foundation School of Engineering and Applied Science.

To teach the vocoder to interpret to brain activity, Dr. Mesgarani teamed up with Ashesh Dinesh Mehta, MD, PhD, a neurosurgeon at Northwell Health Physician Partners Neuroscience Institute and co-author of today’s paper. Dr. Mehta treats epilepsy patients, some of whom must undergo regular surgeries.

”Working with Dr. Mehta, we asked epilepsy patients already undergoing brain surgery to listen to sentences spoken by different people, while we measured patterns of brain activity,” said Dr. Mesgarani. ”These neural patterns trained the vocoder.”

Next, the researchers asked those same patients to listen to speakers reciting digits between 0 to 9, while recording brain signals that could then be run through the vocoder. The sound produced by the vocoder in response to those signals was analyzed and cleaned up by neural networks, a type of artificial intelligence that mimics the structure of neurons in the biological brain.

The end result was a robotic-sounding voice reciting a sequence of numbers. To test the accuracy of the recording, Dr. Mesgarani and his team tasked individuals to listen to the recording and report what they heard.

”We found that people could understand and repeat the sounds about 75% of the time, which is well above and beyond any previous attempts,” said Dr. Mesgarani. The improvement in intelligibility was especially evident when comparing the new recordings to the earlier, spectrogram-based attempts. ”The sensitive vocoder and powerful neural networks represented the sounds the patients had originally listened to with surprising accuracy.”

Dr. Mesgarani and his team plan to test more complicated words and sentences next, and they want to run the same tests on brain signals emitted when a person speaks or imagines speaking. Ultimately, they hope their system could be part of an implant, similar to those worn by some epilepsy patients, that translates the wearer’s thoughts directly into words.

”In this scenario, if the wearer thinks ‘I need a glass of water,’ our system could take the brain signals generated by that thought, and turn them into synthesized, verbal speech,” said Dr. Mesgarani. ”This would be a game changer. It would give anyone who has lost their ability to speak, whether through injury or disease, the renewed chance to connect to the world around them.”
