My OnePlus One heard a video I'm watching

My android phone was on the desk next to me while I was listening to a calculus lecture on my desktop pc.. Suddenly, the phone screen lit up and displayed google chrome providing a search on "chain rule".
I don't feel at all comfortable with my phone now.

What is happening?

Probably heard something that vaguely sounded like "ok google" in the video. If you never use voice search, just disable the hotword response.

Going to echo what Raduque said: if something closely matches the "OK Google" command, it'll start listening for a little bit.

This isn't unique to Google, either. Apple gear and the Xbox One (with Kinect) are known to respond to false positives. We really need voice-specific training to be more common on devices...

Computers and their minions(phones) do like math, what's to wonder about? They want to learn too .
