I am so glad to see an unpolished early look and an honest evaluation of about five percent error rate in the YouTube video. The really cool stuff will be the applications on top of `subvocal` though at least in my opinion.

So this could take "noise canceling" to a whole new level if you could somehow "speak" across a loud bar or across the world, for that matter. Being integrated into something like Signal or similar end to end encrypted platform would be interesting as well.

Yep, I agree. Noise cancellation is a feature we want to release at some point in the future. Using the RF to denoise a very noisy audio signal which has you speaking in it. And we'll release an SDK as well a few months after shipping to build stuff on top of it!
