 In surface dyslexia, words with regular pronunciations (highly consistent with their spelling, e.g. mint) are read more accurately than words with irregular pronunciation, such as colonel. Difficulty distinguishing homophones is a diagnostic used for some forms of surface dyslexia. This disorder is usually accompanied by surface agraphia and fluent aphasia. Acquired surface dyslexia arises when a previously literate person experiences brain damage, which results in pronunciation errors that indicate impairment of the lexical route.
