When reading, we consume whole words at a time, even in syllabic / phonetic alphabet languages.
English is a poor comparison, because it - having consumed vocabulary from many other latin alphabet languages and preserved their spelling, among other historical accidents - does not have a consistent pronunciation rule: you have to know the word to know the pronunciation or otherwise only guess at it, which is similar performance of an ideographic language with pronunciation hints like Chinese.
Latin languages with consistent pronunciation are better examples.
Hangul though, is a superb example: truly designed system, syllabic and compositional. (other readers: look it up, it's really cool how it works).
It's unfortunate you were downvoted over the details here. The big picture - many languages have a large process of rote memorization as a barrier to literacy and such a process is entirely optional - is a great observation.
