is it possible that there are tools available that do the job with minimum energy consumption but they are not out in the open yet?
i wonder what tech military has that we dont know is even possible today?
What do you do about multiple languages? Hiding a speech-2-text dataset in English in the app is one thing, hiding several in multiple languages would make the app bloat.
The military is not at the forefront of R&D, but they may be able to restrict whatever they deem important. For instance, this can happen with patents. Some patents are reviewed by a committee before they are published.
