Do people seriously still think this is a thing?
Literally anyone can run the basic numbers on the bandwidth that would be involved, you have 2 options:
They stream the audio out to their own servers which process is there. The bandwidth involved would be INSTANTLY obvious, as streaming audio out is non-trivial and anyone can pop open their phone to monitor their network usage. You'd hit your data limit in 1-2 days right away
They have the app always on and listening for "wakewords", which then trigger the recording and only then does it stream audio out. WakewordS plural is doing a LOT of heavy lifting here. Just 1 single wakeword takes a tremendous amount of training and money, and if they wanted the countless amount of them that would be required for what people are claiming? We're talking a LOT of money. But thats not all, running that sort of program is extremely resource intensive and, once again, you can monitor your phones resource usage, you'd see the app at the top burning through your battery like no tomorrow. Android and iPhone both have notifications to inform you if a specific app is using a lot of battery power and will show you this sort of indicator. You'd once again instantly notice such an app running.
I think a big part of this misunderstanding comes from the fact that Alexa/Google devices seem so small and trivial for their wakewords.
What people dont know though is Alexa / Google Home have an entire dedicated board with its own dedicated processor JUST for detecting their ONE wake word, and not only that they explicitly chose a phrase that is easy to listen for
"Okay Google" and "Hey Alexa" have a non-trivial amount of engineering baked into making sure they are distinct and less likely to get mistaken for other words, and even despite that they have false positives constantly.
If thats the amount of resources involved for just one wake word/phrase, you have to understand that targeted marking would require hundreds times that, its not viable for your phone to do it 24/7 without also doubling as a hand warmer in your pocket all day long.
But what about a car? Cars are as smart as smartphones now, and you certainly wouldn't notice the small amount of power needed to collect and transfer data compared to driving the car. Some car manufacturer TOS agreements seemingly admit that they collect and use your in-car conversations (including any passengers, which they claim is your duty to inform them they are being recorded). Almost all the manufacturers are equally bad for privacy and data collection.
