A reader gets the hints based on sound-symbol correspondences to decode and comprehend the text. What is this known as?

Graphophonic cues refer to the relationship between graphic symbols (letters/text) and phonic (sound) representations. When a reader uses sound-symbol correspondences to decode print, they are using graphophonic cues. 'Grapho' (writing/letters) + 'phonic' (sound) = sound-symbol correspondence. Graphic cues alone refer to visual features; syntactic cues to sentence structure; metalinguistic cues to awareness of language.
