Yep, he needs to slow down and articulate each word distinctly. And he needs to pay attention to his tendency towards, what I think is called, prothesis; where he, quite frequently, attaches or echoes the final sound of one word to the beginning of the following word. It's very annoying. I know we probably all do it in common everyday speech, but even in a language that you are planning on speaking on a regular basis--which Latin is not, for me at least--in the early stages of learning, which this is, clear articulation of each word distinctly is not only appreciated but helpful. And the opposite is frustrating. The other speakers seem to be able to do this halfway decently.
I feel like this course takes a very different approach to Latin than most school courses. Latin breaks all of it's own rules, and interpreting text to match a key is not always simple, even if you do know all of the rules. That being said, I only had one issue so far, so the programmers have been doing a good job allowing for differences in linguistic order.
āra f (genitive ārae); first declension, "altar". From āsa, ultimately from Proto-Indo-European *h₂eHs- "to become dry; to burn". Related to English arid, and Spanish arder ("to burn") and asar ("to roast"). Also related to star, astral and stellar, English words of Germanic, Greek and Latin origins. Other cognates include Ancient Greek: ἄζω (ázō, “to dry”), Hittite ḫāššā- (“fireplace, hearth”), Sanskrit आस (ā́sa, “ashes, dust”), Tocharian B astare (“pure”), Welsh odyn (“kiln”), and, last but not least, English arson and ash.
