Brain-machine interfaces implanted in the participants of this study in the supramarginal gyrus (SMG) and primary somatosensory cortex (S1) were successfully able to decode both internally spoken and vocalized words.

The article said surgery. Also common sense, they are reading individual neurons. Not feasible from outside.

Best we have is FMRI, and it is an amazing technology, but it absolutely can't do that and never will because of how it works. And besides, it doesn't fit in a doorway either, and would also be incredibly obvious: loud, super magnetic - requiring all metal to be removed for a long distance, requiring the target to sit for a long time and follow instructions, etc.

Surgery is absolutely the only way this is possible.
