I started with "statue", then thought it would be "sculpture" because of the theme of the exercise!
Is there something wrong with the recording here? The last two words seem very strange
It sounds ok to me. Of course, I know what to expect which might color my observation but still I think it is clear. Perhaps, there is a bit more rolling of the "ρ" in "αριστο" but not abnormal or incorrect.
It sounds okay to me too, but as Jaye said, it might be the rolling ρ that's confusing you. We've noticed that issue with a couple of sentences. ^.^
For me the άριστο was clear, Duo always pronounces it the same way, but ο άγαλμα, sounded as if there was an extra syllable η between the λ and μ
The sound is pretty clear but still it sounds very nonhuman, kinda robotic...
