I doesn’t work like that… it is also not the same as the “inner voice” they talk about when they dumb it down in their books and articles, because they’re afraid people won’t understand what is meant by “subvocalization”.
Again, not what is meant… they mean the voice that is “reading along” word for word… not an inner monologue that explains on top of the written text. The idea is that your vocal chords (used during subvocalizing) will put a limit on how fast you can go because they can only produce sounds so fast.
That is way too slow if you want to not subvocalize what you read. Imagine trying to run at 2 mph… your brain would be very confused as to why you’re not just walking instea, because you’d be twice as fast. Try reading at 3-4 times of what you’re at.
Where did you find that technique? You’d read in word clusters when speed reading, not the first letter of each word. You’d also skip useless words like “de” in Spanish.
esp: zumo de naranja, zumo de manzana, zumo de piña → z d n, z d m, z d p
eng: orange juice, apple juice, pineapple juice → o j, a j, p j
deu: Orangensaft, Apfelsaft, Ananassaft → O, A, A
Especially, in Spanish you should be able to see the word cluster and just read it as one piece of information, same for English and German because the construct is familiar to you. Following this first letter technique… English speakers should be able to read twice as fast and German speakers three times as fast as Spanish speakers.
It would probably slow down English or German speakers a lot if they found “juice of oranges”/“juice of the orange” or “Saft von Orangen”/“Saft der Orange” instead. Even though grammatically perfectly okay, but your brain is not familiar seeing this construct every time you’re in a supermarket.
see here… not all texts are equal:
Bottom line, if on top of memorizing you are also learning new concepts during reading then forget about speed reading.
It’s actually exactly the same: replace the abstract with a concrete image and store it in a location in your memory palace. You’re making use of image recognition and spacial navigation.
Instead of trying to review fast(er), try to review more effectively… spaced repetition software like Anki or Memrise can be used for that. Also active recall is more powerful when it comes to retention than just re-reading your notes is.
