I think you're talking about subvocal recognition [1]. People are indeed using ML for it, but it looks like it's more complicated than it appears. Still, I think it's only a matter of time before it's available to the average consumer, which I can't wait for because I've wanted something like this for a long time. I do my best thinking when I'm hiking, and I'd love to be able to dictate my thoughts on the move without looking like I'm talking to myself out loud (even though I am, I guess) in public.

Several years ago, I was on a long solo drive and thinking about how I would like to be able to communicate with my computer in a subvocal manner. I stuck my pinky finger in my ear canal and "listened" to the deformations of the canal as I spoke, and thought "with a deformation scanner and good machine learning, this could totally work". Later, I registered the domain silentbuds.com to trial the idea but never pursued it. Just did some Googling and see that there are a few new research papers on this approach.
