No one has the storage capacity necessary to store that much audio content, let alone video. Furthermore, the incremental benefit over traditional ad targeting via search or web history is probably pretty marginal, and not nearly worth the effort/cost. All of these scenarios (Jake Jacobs' wife, Jeff Jone, Jennifer Smith) are already going to show up in a traditional search history, why would an ad company go through all that effort to get data they already have? This is real life not a Mission Impossible movie.
