Based on anecdotal experience, giving a smartphone app access to your microphone "while using the app" results in targeted ads for things you were talking about within 10-15 minutes of having the app open. I haven't done any strict science to confirm it, but I'm obsessive about privacy and can almost always track down the likely reason when I get an accurately targeted ad. I'm my opinion, it's naive to think that our voices aren't being processed by tech companies to serve ads at every opportunity. I'm glad to see some analysis proving it, and I think we need more of that because the problem definitely isn't limited to Amazon.
