Eli5 Why is it so easy for us to tell the difference between a real voice and a recording of a voice?

For example, how do our ears easily discern that someone talking in a room is actually there vs the dialogue coming from a television is not physically there?

Your brain is hardwired to detect human voices more than other sounds. However, your tv speakers don’t output all frequencies, the editing and broadcasting will compress the audio and shape the frequencies in an unnatural or low quality way for file size, style, etc.

If you got a high quality recording of someone and played it back on very high quality speakers in an environment where you aren’t aware of a speaker in the room. You’ll be fooled pretty easily.
