I’ve never dealt with this using a hypersonic speaker but I’m very familiar with attempting to record lyrics while hearing my own voice on a delay and it’s impossible. Thinking about just trying to read text while hearing myself on a delay sounds similarly difficult.
My guess is that some of us, musicians especially, are more reliant on internal timing in all things.
