This is a most excellent place for technology news and articles.
This is a great case of confirmation bias, too. The one time your ad happens to match a conversation you had earlier, you’ll be convinced forever, and tell everyone you know about it. The ten million other times you have a conversation that doesn’t appear in your ads will go unnoticed.
Ads aren't why you should be concerned about apps w/ microphone access...
Where exactly are you getting the idea that this belief is widespread?
"Is it Apple though, probably not..."
Can I ask, why are you so ready to performatively forgive them here? Apple is not your friend, Apple and Tim lined up to donate the million like the rest of those greedy, transactional cowards.
Apple doesn't "do" it per se, instead Apple shares certain data with third party partners for the purposes of "improving your product experience" the data is then laundered 17 times through middle layers and added to a shared digital fingerprint of you and your household's web of connected devices. You and your family are then sold on a marketplace as advertising targets actively interested in X category or product (Apple is also subsequently a customer in that marketplace). You then either receive that advertising or your family is targeted with it so that they can then casually mention the product back to you (company knowing you were already interested) so it feels organic and "I was just thinking the same thing!" and boom, you're buying that new set of pots and pans.
We're already living in the matrix, you're just a little drone being pinged around according to other people's will, to support the pursuit of endless growth. So yes, in a way companies are spying on you... After you've given them individual permissions to access your microphone and permission to share "certain data" about you with third parties, in a carefully orchestrated dance - so that they have plausible deniability and so you don't have to threaten your parasocial relationship with their brand and can continue saying "probably not Apple though..."
Two ways to process voice, on device or on server. Device-based solutions either are very basic and just detect differences between words or need training data based on your voice or they need lots of processing power for more generalized voice recognition. So is your battery draining and phone is often hot because an app is keeping the mic on and keeping the phone from slowing the processor? Other option is to stream the data to the server. This would also increase battery usage as the phone can't sleep, but might not be as noticeable, but more evident would be your phone using a lot more bandwidth than is reasonable while you aren't actively using it.
They are absolutely listening. This is very easy to test. Speak around a Google or Amazon or Apple device, and start talking about things you would never buy, never need, have never looked up, and is completely irrelevant for your demographic. You’ll get ads for it anyway by the end of the day or week.
Listen to the Big Tech comments to press and congressional testimony very carefully. They always say something like, ‘Facebook is not spying on your microphone.’ They’re always very carefully wording it as the parent company is not listening to your devices. But they absolutely know either one of their subsidiaries or their partners are listening to your microphone, and feeding the data to them.
