Echos and Homes are natural-language understanders that remain on in people's rooms. I know I didn't cite Google except via YouTube. Google Fi, Google Voice are...who knows, but I'm pretty sure your call contents are available to them. But by "more" I didn't necessarily mean a superset; I meant a greater amount of stuff: your email, your postings, your messages to your friends, when you do stuff, where you've been, etc.
Try "Google Pinpoint". That system seems to be the static extension of what Google has in audio to text to relevance conversion.
