Here's another thing for humans to try. If you can set this up it's very intriguing.
Get a good set of headphones (not buds) and feed them the signal from a mic. Put a variable delay on the signal being sent from the mic to the phones, something like 0.5 to 1.5 seconds.
Plonk yourself in front of the mic and turn the system on.
Now......try to talk properly. Vary the delay, just for play value.
This might lead to having some sympathy for those people you sometimes see on TV "crosses", who sound like idiots. 😧
