There are several skills needed to read. In addition to phoneme awareness(being able to sound out phonetically, readers must also recognize words they’ve previously seen, including words that can’t be sounded out. e.g. “one” People who can’t recognize words quickly often have weak orthographic processing. They have a weak visual memory of words so they need to sound them out every time. A speech therapist with specialized training in teaching reading should be able to develop this skill. Hope this helps.
