For example, in a video taken at the beach where someone says “wow that looks fun” (in any language) and there is a boat in the frame, you could serve them boat ads.
But go ahead, try it yourself! Have a conversation about having children with your loved one, next to your phones and your TV box, no online search required. Give it few hours and turn your Sling on, or browse some Amazon/Youtube. All of sudden you will see ads for products and companies you have never heard of, trying to sell you diapers or baby cribs. Where do you think it came from? Google, as of today, still is unable to read your mind.

1) we know that sending voice data to "HQ" costs power
2) we know that live transcription costs a huge wedge of power
3) we know that wakeword matching is quite power efficient. (see https://rhasspy.readthedocs.io/en/latest/wake-word/, https://github.com/MycroftAI/mycroft-precise)
So, in a quite room we know that to save power and data, devices won't be streaming data/listening. We can use that as a baseline for power and network usage.
Then we can start talking, measure that
then start saying watchwords and see what happens.

There are quite a few searches/website visits that strongly correlate to life events. Humans are not as unique and random as you may think, especially to a machine with perfect memory.
You not going to distinguish what people want to BUY from Google search as good as from conversation. When I google "Ferrari" it may mean I am looking for Ferrari wallpaper, Ferrari stats, Ferrari parts, or want to buy new Ferrari. When I have a conversation with someone about buying Ferrari, the conclusion IS I am ready to buy a Ferrari.
