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.

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. ```
