>>24498080It's just a skill like any other. Being able to subvocalize doesn't mean that you never subvocalize.
If you're doing academic work that requires you to find relevant information in twenty 400 page books, then I'd like to read them over quickly and save time for attentively reading the books and sections that are actually pertinent to what I'm doing.
If I'm reading a complicated book, I'll slow down and subvocalize, if I'm reading a disposable murder mystery for plot alone, I won't subvocalize.
