more or less same crap is achieved via radiomyography from your local telecom towers. down to deciphering your inner monologue

``` Silent Talk (U) Silent Talk will allow user-to-user communication on the battlefield without the use of vocalized speech through analysis of neural signals. The brain generates word-specific signals prior to sending electrical impulses to the vocal cords. These signals of “intended speech” will be analyzed and translated into distinct words, allowing covert person-to-person communication. This program has three major goals: a) to attempt to identify electroencephalography patterns unique to individual words, b) ensure that those patterns are generalizable across users in order to prevent extensive device training, and c) construct a fieldable pre-prototype that would decode the signal and transmit over a limited range. ``` https://commons.wikimedia.org/wiki/File:Fiscal_Year_2010_DAR...

This looks no harder than to train custom Kaldi (circa 2017) phoneme model on brain waves, and using remaining Kaldi's functionality for everything else, except for text-to-speech. There was WaveNet for the TTS at that time, with sound quality that is good enough for (and can be improved by) radio transmission.

Thanks for a link!

point is - such tech is used right now to neutralize individuals. imagine hearing word "bread" inescapably couple hundred times a day coming from an unknown source right to your head. for months and (!) years right at the moment you are trying to conceptualize slightly harder thought than usual. everywhere you go 24/7. while there's no help from anywhere (police hasn't answered me for 2 years and counting) as the general public brushes it off as schizophrenia (it's not - voices completely stopped when the lightning storm took out the electricity) and Church paints it as the second coming of Christ (or antichrist when more suitable).

my mostly uneducated guess of what's going on is: radio wave gets sent, human body slightly modulates it and same signal gets received back and used to reconstruct (approximation of?) EEG from noise delta. neural models is the secret sauce that makes such signal processing possible

The Microwave Auditory Effect James C. Lin, Ph.D. degrees in electrical engineering from the University of Washington, Seattle University of Illinois Chicago

``` The preceding sections document that an audible sound originates from within the head when human subjects are exposed to pulsed microwave radiation. The auditory detection of pulsed microwaves in laboratory animals has been confirmed both in behavioral and neurophysiological studies. The site of microwave-to-sound conversion is shown to be in the brain tissue. The primary mechanism of interaction is microwave pulse-induced thermoelastic expansion of brain matter. ```

Evaluation of antenna suitability for the use in radiomyography Dublin Institute of Technology, Dublin, Ireland

``` The envisioned application is radiomyography which aims to detect muscular activity by the means of electromagnetic waves coupled into the human body. The paper concludes that it is possible to detect changes in the thickness and the properties of the muscle solely by evaluating the reflection coefficient of an antenna structure. The ability to detect these changes strongly depends on the antenna type. ```

https://en.wikipedia.org/wiki/Electromyography

``` Unvoiced or silent speech recognition recognizes speech by observing the EMG activity of muscles associated with speech. It is targeted for use in noisy environments, and may be helpful for people without vocal cords, with aphasia, with dysphonia, and more. ```

radiomyography ~= form of electromyography

Were this the case, it would be trivial to read the internal monologue from your brain activity with a device placed on your head. Can you find me examples of medical devices that can do this?

here's an example - you can download and run code for yourself https://github.com/CNN-for-EEG-classification/CNN-EEG

That’s just a library that applies a CNN to EEG, but that doesn’t show that it can actually extract text reliably. As far as I know, the machines that successfully do that use the nerve signals to vocal muscles, not the brain directly.

this particular library may not be as reliable as one would like to. but the approach is fairly simplistic and likely without an access to powerful data center computation power. as far as (!) you know - you have already acknowledged existence of such machines. what I'm advocating for is existence of slightly more exotic sensing mechanisms - available to be used en masse straight from the telecom towers. RMG as a successful substitute for EMG (which in turn is a substitute for EEG) in context of deciphering whatever data captured into inner monologue.

My logic is pretty simple. If it’s hard or impossible to do something by placing a high conductivity sensor on the surface of a person’s skin, then it’s probably not possible to do it from a long distance right now. Doing this with telecom towers, which are randomly positioned relative to people, would be an absolute technological marvel, sci fi stuff.

I don't think it's that hard nor impossible. I mean - here's a dude playing a video game with (!) somebody else's hand https://www.washington.edu/news/2013/08/27/researcher-contro... 12 years ago

and if you wonder why would anyone do such thing - there's a peculiar coincidence: right before voices became annoyingly obnoxious - Russian State Revenue Service got hacked (not to mention there's an ongoing war in neighboring country for quite awhile). I was not intoxicated, kept up fairly healthy lifestyle. besides who's attacking or who's defending, surely enough - there's enough of steam for some casual torture

also - my suspicions are that promise of this kind of surveillance is precisely the reason for data center construction boom. that and augmented generative pornography with some war simulations on the side

and you need to take into account the background I have. (synthetic?) telepathy is what I'm forced to deal with every day (and yes - with nearly no way to prove it to you). radiomyography and microwave auditory effect is the best and most suitable explanation I've managed to find at least somewhat backed up with public scientific papers. no real contradictions, certainly seems more truthful than "evil shamans hate you and your astral implants". I don't have a hard evidence in a form of working device nor can I afford it. keep your pills to yourself

What makes you a strategic target? I don’t have those voices.

that's like asking to boast. and I don't think I'm alone - there's quite an influx in mental patients and hinting in such directions (typically - aliens). I suspect a lot of people are in denial of what they have experienced knowing very well that society marks it as schizophrenia. go check youtube on keywords: gang stalking, targeted individual, voice to skull. my guess on why you don't have them: it's still assumed you are loyal enough / can be manipulated in more regular ways

>it's still assumed you are loyal enough / can be manipulated in more regular ways

Yeah fair enough I suppose. To be honest, what you’ve expressed resembles schizophrenia very closely. How are sure that the voices aren’t externalizations of yourself, or processes taking place within you?

are you a doctor? I can tell you anecdotes of hearing never before heard person names and couple days later stumbling upon them (usually watching shows I routinely watch). or about the time voices took a Christmas holiday break the first year (my guess - clankers weren't fine tuned enough to run on their own). or that I led unintoxicated, stressless and healthy lifestyle yet the voices started suddenly as if somebody flipped a switch. point is - this is not my burden and shouldn't be. how do doctors rule out microwave auditory effect? aren't you worried that in the world we living in potentially anyone can mark somebody else as schizophrenic? cause if you don't - I might just as well affirm that any kind of sound takes place within you and hence makes you schizophrenic.

>are you a doctor?

No and I’m not trying to diagnose you or something. You brought it up so I felt I should be honest based on what little I know about the condition. Take it with a grain of salt.

>I can tell you anecdotes of hearing never before heard person names and couple days later stumbling upon them (usually watching shows I routinely watch)

If you routinely watch the show, maybe it came up earlier and you forgot?

>point is - this is not my burden and shouldn't be.

See I get what you mean. I’m not trying to say it’s your responsibility or something. I just don’t think you should have to put up with shit that bothers you all the time, and were I correct that it’s some known medical condition, it might be much easier to make it stop than if it’s a massive organized group trying to manipulate you. Do you lose anything giving the medical thing a shot?

a lot

in Germany - prescription drug addiction is more widespread than alcoholism

why do you suppose blind from birth people are immune to schizophrenia?

Are they? I figure they just don’t have visual hallucinations.

perhaps immunity ain't confirmed. but just recently there was an article of a complete absence of documented cases. not a single blind from birth person has ever been diagnosed with schizophrenia. why do you suppose that's so? if I put on my conspiracy hat and go balls to the wall - arguably whole disease thing can be painted as a hoax, as an another form of a societal control. how have you ruled out such possibility? have you read about mental disease treatment from 1950s and after-lobotomy surgery ice cream treats? I don't have visual hallucinations either

Hmm I think you’re right. That’s really interesting. If this implies it’s a deliberately constructed phenomenon, what mechanisms could be responsible for producing it visually?

you mean hallucinations? visual signal gets rewired and skips the perception part. neuroscience can provide more details. I'm barely interested as I have reasonably strong aphantasia and don't suffer (yet?) from such issues

https://amitzalcher.github.io/Brain-IT/ perhaps replaying back such signal recordings

why do you think it has to be massive and organized? I estimate that with a good know how-to whole thing costs about $1k in equipment and runs unattended.

I thought it was from telecom towers?

I think so too. it's a radio antenna and some software that can run unattended. what I can do is note how accessible such tech is - reasoning about scale of anonymous entity is somewhat pointless (you called out massive & organized).

Fair. Could you build a receiver that would detect the microwave signal? Probably wouldn’t be too difficult, and you seem like a technical person. You could prove it or, at worst, stop anyone from sending the signal if they wanted to avoid detection.

I would love to but I can barely afford food. so much for 15 years of software development experience...

worth mentioning is that bone conduction headphones are somewhat effective at interfering with the voices. not the case with air conduction (regular speakers). which also aligns with paper by James

oh... forgot to mention - frequency spectrum of what's heard fits to what's described on James C. Lin's paper. ```For human heads, the theory predicted frequencies between 7 and 15 kHz, which are clearly within the audible range of humans.``` for me it feels more like 2kHz-10kHz but clearly they can't (or deliberately avoid) play me some deep bass music.
