I was surprised all that made it into the demo video. Did not seem cool. Is that "active listening" or something?

Its actually useful, when you are launching into a long monologue and want periodic acknowledgement that its "listening".

I have now had a chance to use it, and it never interrupted me. Weird call for the video to include that. Works very well, and can even mash up languages.

I think it would make me stop speaking. I guess it might take me some time to get used to it.

I think it just doesn't know when it's its turn to speak, and cancels itself out when it hears humans.
