For myself I can learn a written word without having any idea of how it is pronounced. Growing up there were multiple occasions when I was speaking and mid way through a sentence realize I don't know the pronunciation of the next word I was going to say.

Also I can read text and completely miss rhymes unless the formatting draws attention to it like how poetry is often written with lines split. (More likely to miss rhymes like half and graph where the word endings visually are different.)
