Yea in one of the further Ender's Game novels they talk about this tech a lot for characters silently mumbling to the AI.

I second that. I've been talking and talking to my phone and AI even more and more since it keeps getting better and is generally pretty accurate these days. And there are times when I end up typing because of environmental reasons.

This is just really groundbreaking and I know the research has been out there for a little while but to actually implement is a whole nother ball game.

I think the use cases for this will expand as the product ships and gets out there!

Agree, incredibly cool, and I could definitely see myself using one, but it does give off slightly dystopian vibes, making me think of the speakwrite in 1984:

"In the long, windowless hall, with its double row of cubicles and its endless rustle of papers and hum of voices murmuring into speakwrites, there were quite a dozen people whom Winston did not even know by name"
