You normally think of fiber optic as something used in network cables. However, scientists employ dedicated fibers to detect earthquakes. In simple terms, they fire a laser down the fiber and watch…
Besides, if researchers can do this successfully, you would imagine three-letter agencies around the world could do it even better.
You can’t just listen to a random fiber on the switch. You’d have to prepare a piece carefully and add the measuring system, by which point a micro is easier and smaller.
There was a demonstration of this where they had loops set up around a building simulating a network distance. They put music on a phone and walked to a distance they said was some kilometers away and were able to pick up the music without issue.

Yeah, it basically says, “researchers could potentially measure vibrations in the air to detect speech.”
I know. That’s how speech works.
