I doubt this could ever be used to arbitrarily read minds. Even if you could do the measurements without the targer knowing, you would have to somehow correlate the target's real thoughts with those measurements. In the article, the targets voluntarily provide that correlation to measurements during a training phase. It might be the case that some neuro-physical patterns might be common across targets, but that seems very unlikely.
If the target is in your custody and you coerce him to give training data, then he could just give garbage data. You tell him to think "fish barrel neuton whale", but he really thinks "somebody once told me".
Do sub-vocalizations only occur for certain categories of thoughts? I suspect that facial memories do not induce sub-vocalizations.
