I wonder if the same is true for languages where the writing system is not a representation of sounds, like written chinese.
I wonder if native speakers have a greater emphasis on subvocalized pitch, or if that’s even a part of subvocalizing? Paying attention to my own internal reading now, I suspect that it is.
The intonations that give the characters their meaning are so engrained in the flow of the sentences it can feel monotone, as it is just the way it is said.
If I am reading a poem or idioms I usually like to over emphasize the tone like a classic theatrical reading because it’s fun and helps me remember what I read.
