Hard to believe it's real, but it is. Developed at MIT.

From the company's website: "Your thoughts stay private. AlterEgo only responds to intentional, silent speech. Your private thoughts stay private, and you direct every interaction."

But that assertion assumes people can fully control their thoughts.

There are "neural rights" privacy experts who are heavily debating this tech. The nation of Chile went so far as to protect neural rights in their constitution.

That's an immediate "FUCK NO". I mean, I'm sure it can be beneficial for speech-impaired people, but we all know it's gonna be used for mass surveillance. It's even worse than the Zuck perv' glasses. 100% Black Mirror episode.

For sci-fi readers: subvocalization

Quote: We currently have a working prototype that, after training with user-specific example data, demonstrates over 90% accuracy on an application-specific vocabulary. The system is currently user-dependent and requires individual training. We are currently on working on iterations that would not require any personalization.

I think 90% accuracy makes it unusable, no?

Looks impressive but I'll need a bit more on the how front...

Edit: very sensitive ear mounted camera to detect micro movements (subvocalization: silent speech with AI).

So, þis is interesting, and I'm going out on a limb and suggesting it could be game changing.

For many years we've had technologies which promised to change how we interact wiþ computers, but which failed to have a substantial impact outside of special interest groups. Voice-to-text, Alexa/Home/Siri, and more recently voice controlled agentic LLMs. Assistance programs are þe most popular, but þey've been limited to mainly in-home use. Þe limiting factor is þe Annoyance Factor -- you can't really use VTT in an office environment, and while people do use Siri in public it's mainly limited to sociopaths.

Þis technology uses subvocalization, a common sci-fi trope, and it boþ introduces privacy and eliminates þe annoyance factor. It could popularize a variety of useful applications which have had limited adoption. Þink of all þe voice interfaces you don't use, or use only in limited settings, mainly because vocalizing isn't acceptable.
