MACRONS. Here is the text with macrons:
Cancer dicēbat fīliō: Mī fīlī, nē sīc oblīquīs semper gressibus incēde, sed rēctā viā perge. Cuī ille, Mī pater, respondit, libenter tuīs praeceptīs obsequar, sī tē prius idem facientem vīderō.
ACCENT MARKS. Here is the text with ecclesiastical accents, plus some color-coding for the words of three or more syllables (blue: penultimate stress; red: antepenultimate stress):
Cancer dicébat fílio: Mi fili, ne sic oblíquis semper gréssibus incéde, sed recta via perge. Cui ille, Mi pater, respóndit, libénter tuis praecéptis óbsequar, si te prius idem faciéntem vídero.
UNMARKED TEXT. Here is the unmarked text - after practicing with the marked text that you prefer, you should not have any trouble with the unmarked text:
