Yes, this a step towards technological telepathy. Something that hasn't been tried as far as I know is to design a new human language from the ground up with only phonemes that are easily distinguishable when spoken silently. That is, first we figure the kind of signals that are well separated by ML interpreting EMG output on the throat when subvocalizing a range of sounds, and then we build a conlang using only the precursors to these signals. Possibly this conlang could then be parsed and translated and the recipient of the message could hear their native tongue instead. It could start as a computational language at first, only used to send commands and control to software, but then it could be expanded with more nuances and human-centered constructs.
