Your argument plays with the idea that the phone listening stuff is the only source of information for the ad networks. But it would be much more complex. It would be only one of many signals, that are used to serve the consumer the right advertisement in the right moment. So it doesn't need to have the exact phrase "pool fencing" in the database. It just need to detect that something about pools, or swimming, etc. was talked about. Since Google has thousands of signals and statistics (like browsing history, current location, the other smartphones that are near, and those histories etc.) about this person, it can sell the ad space to "pool fencing" and expect a high click through rate. Selling ads is a bit like the current LLMs. It's just a stochastic parrot, that hallucinates stuff. But the stuff is often that advertisement that brings in the most money.
The self-expressed goal of this kind of test is to pick a phrase or topic that is so random that it escapes that person's existing ad data profile. As the comment above said, "He doesn't own a swimming pool, doesn't want to, and has never expressed any desire to."
So showing that person an ad for pool fencing is a complete waste; they're never going to click it. If that's what an alleged audio targeting system does, it would make the ad network less profitable than just using the data they already have. So why would anyone build it that way?
