> 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.

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
