It's Ancient Greek pronounced like Modern Greek. Ancient Greek had certain sounds and a rhythm that are quite distinct and recognisable. For example, the presence of diphthongs, aspirated voiceless stops and the production of beta as /b/ rather than /v/ or the /h/ not being silent. All of these are easy markers that the pronunciation is at least more correct.
