Could use an “auctioneer” voice to playback text at 10x speed.
I understand 4-6x speakers fairly well but don't enjoy listening at that pace. If I lose focus for a couple of seconds I effectively miss a paragraph of context and my brain can't fill in the missing details.
I wonder if there is negative side effects of this though, do you notice when interacting with people who speak slower require a greater deal of patience?
You are basically training your brain to work faster, and I suspect that causes some changes in the structure of your memory; if someone speaks too slowly, I'll be more likely to forget what they said earlier, compared to if they quickly gave me the entire sentence.
