I am confused about the correct pronunciation of consecutive vowels - I have several recordings (both from Cambridge University Press and Bolchazy-Carducci) that include a glottal stop between the two vowels in words like "mortuus" or "filii." But "Vox Latina" does not seem to mention an intervocalic glottal stop (I will cofess I've only browsed the book, not read it cover to cover).
I am willing to accept the glottal stop if it's correct, but it sounds awful. I speculate they use it in recordings to make the point that the vowels are separate syllables. Can anyone clarify?
