I'm not going to say it's not technically possible, because it is (although it would be a huge battery or bandwidth drain, not to mention an insane tech scandal if found to be true); but if the only proof you have is a video feed that resembles your conversations I'm going to guess you're giving that data to Google is some other way. There are a thousand ways this could be happening, and most them have a psychological component.

I've made significant efforts to minimize dependency on google services and these are items that appear w/o any interactions or data being explictly shared to the google platform. It was hard to believe at first, but after quite a bit of testing I realized what was happening.
