READ OUT LOUD. Choose which marked text you prefer to practice with - macrons or accent marks - and read the text out loud until you feel comfortable and confident. Then, try reading the unmarked text at the bottom. It should be easy for you after practicing with the marked texts. :-)
MACRONS. Here is the text with macrons:
Pīca et columba pāvōnem convēnerant, ut eum salūtārent. Dum revertuntur, maledica pīca Quantoperē (inquit) mihi displicet pāvo! Quam īnsuāvēs ēdit sonōs! Cūr nōn silet? Cūr nōn occultat pedēs dēformēs? Cui rēspondit innocēns columba: Vitia eius nōn observāvī, vērum formōsitātem corporis caudaeque nītōrem adeō mīrāta sum, ut nōn possim eum satis praedicāre.
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):
Pica et colúmba pavónem convénerant, ut eum salutárent. Dum revertúntur, malédica pica Quantópere (inquit) mihi dísplicet pavo! Quam insuáves edit sonos! Cur non silet? Cur non occúltat pedes defórmes? Cui respóndit ínnocens colúmba: Vítia eius non observávi, verum formositátem córporis caudaéque nitórem ádeo miráta sum, ut non possim eum satis praedicáre.
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:
Pica et columba
pavonem convenerant,
ut eum salutarent.
Dum revertuntur,
maledica pica
Quantopere (inquit)
mihi displicet pavo!
Quam insuaves edit sonos!
Cur non silet?
Cur non occultat pedes deformes?
Cui respondit innocens columba:
Vitia eius non observavi,
verum
formositatem corporis
caudaeque nitorem adeo mirata sum,
ut non possim eum satis praedicare.
