This happened to my girlfriend and me twice on Messenger. On two consecutive nights, we heard a male voice with an American accent speaking as if he were talking to someone else, almost like they were conducting some kind of operation. It seemed as though he suddenly realized that we could hear him, after which the voice abruptly disappeared. The following night, it happened again, but this time the voice sounded like that of an African American woman. The situation was similar to the previous night. From that night, we have not used it to communicate and used Signal instead.
I work on products that feature live monitoring capabilities. There's no connection to the monitoring side's microphone (or camera) — why would there be? I'm not sure why there would be for their products.
Whatever the cause, it sure sounds like it was a strange and unnerving experience.
One time when I was in Hawaii I could swear there was a club playing dance music quite loudly somewhere a few blocks over: there was that muffled quality to it where I kept trying to pick out the song from inside my Airbnb.
Walking outside (after asking my wife if she could hear it): silence. Trees rustling, normal noises.
It was background noise. But inside the apartment that combination of different sounds was just right that it sounded like muffled music to me - but hence why I couldn't identify it, whatever was there was just me thinking I was hearing things.
Draw ones own conclusions about the relative technical plausibility of the events described by the OP (how would digital packet based audio experience a glitch which is structured as though you'd tuned into another analog radio station? It wouldn't: that doesn't happen and it isn't even a failure mode).
I usually do night walks, talking to strangers, outcasts such as homeless people, street children, store or restaurant sales persons. I treat them food and talk with them and learn from their stories, I do this consistently that they know me. I genuinely love helping people, I also do ministries which I can say is very effective on helping people with depressions, they will learn to have a purpose in life or at least they will learn that some people are living life with much difficulty. I organize people I do not know and play sports I do not know how to play, and ask people to join. We do monthly activities which is optional for others to join our not. Nothing is forced but every one is welcome.
I do think it's worth separating two things, though. Helping others and building community can be deeply meaningful, but not everyone who's lonely has the capacity
Regarding Facebook is listening, my girlfriend and I was taking few years back around 2021, we usually keep our call for more than 24hrs at a time. One evening we were talking then suddenly we heard a man, talking as if he is in an office then we both stopped and listened, and he just stopped as if he accidentally unmuted. This happened again the next, night but this time it is a woman. Same, as if they were in an office environment. They were talking in English, we are not listening to anything, we were just talking then suddenly we heard them, and also we are not a native English speaker, we do not talk in English during our call. That is the the time we decided to switch to Signal, which as many say is more secure.
