But detecting “oh, this is voice” is easy. Recording the time where that happens is also easy. Knowing when people are chatting around the phone, and roughly what the fundamental frequency of their voice is, could make $0.001 per person. At Google's scale, that's worth it.
So long as they don't get caught, anyway, because that's all sorts of illegal. Especially at Google's scale. (I don't think Google does this… probably.)
What's you're saying is possible and what we're talking about are two entirely different things though.

The fundamental frequency of the voice doesn't tell you what words they were saying.
Actual nlp parsing all audio, or even a tiny subset of devices, is far beyond Google's capabilities. It's not a trivial task to process.
Your phone locally has some extremely basic recognition for "ok google", after which selective actual nlp parsing takes place.
