> The two biggest hardware challenges are reducing the size and weight of the ultrasound probe and replacing ultrasound gel with a more practical coupling material, such as hydrogel. We think both are solvable, making it possible for the probe to eventually become a lightweight wearable or adhesive patch.

Not sure I'd want to put an adhesive patch on my neck every morning so I can silently talk to an LLM in the cubicle farm. I hope this is not our future.

Very cool tech though and surprisingly good results for so little training.

I think time might be better spent improving a lip reading model (no adhesive required), assuming we're unable to read brainwaves directly.

Wonderful tech, and video example. I think there may also be a special forces application, but I don't know enough about how well their current solution works.

In the office, a non-contact video solution (lip reading) is likely to be far more popular, but a lot depends on which is more accurate.

Keeping a camera focused on the lips could get awkward. A hands free throat patch may be more ergonomic.

I wonder if, like with lip reading, they switch from American English to a different language that's not so peculiar they would have and much less error rate

reminds me of the handwriting recognition language Graffiti from palm/handspring days.

It ended up altering my handwriting even after I stopped using it.

I suppose Spanish or German would be easier to recognize than English, due to the more distinct sounds, but Chinese would be much harder, due to the tones.

That could be immensely helpful for people who cannot speak due to vocal chord problems.

It could also be the ultimate, always-on remote control for everything around, with a near-zero error rate.
