“What would it mean for your business if you could target potential clients who are actively discussing their need for your services in their day-to-day conversations? No, it's not a Black Mirror episode—it's Voice Data, and CMG has the capabilities to use it to your business advantage.”
If they were to listen for a set of predefined product-related keywords as well, they could take note of that and send that info inconspicuously to their servers as well without sending any audio recordings. Doesn’t have to be as precise as voice command recognition either, it’s just ad targeting.
Not saying they do that, but I believe they could.
