> Just because someone says "OK Google, whats the weather?" doesn't mean there isn't a conversation going on in the background that they can pick up on. And filtering out the background conversation is a difficult problem in machine learning, but one that has to be accomplished in order to make the service work correctly. We don't store the audio, much less the filtered-out noise, but I don't imagine there's any way I can prove that. Maybe an appeal to cost? There's way too much data to do that, even if we wanted to. The parser output (text) is stored, mind you. You can find that on the Google dashboard.

Storing the data no, but text output as you’ve mentioned, or even passing it into some algorithm that update your profile with some signal that “may be interested in...” is entirely possible with minimal data requirements. And I’m not saying Google or Amazon are doing this today. If not then it may be one bad earnings call away for some engineer to say “well....we could...”. Anything is possible in the pursuit of profits. I’d Google is willing to buy users offline credit card transactions to link to their profiles, it’s clear they will slurp up all data available for them. Why not that listening device in people’s home? “Overheard user X saying they signed up at google-ads-customer.com” “overheard user Y saying google-ad-customers service is fantastic”
