the speaker on this sounded like she was saying "e lupus" not "an obair". I know we've got to get used to accents and personal eccentricities, but the inconsistency of pronunciation in the spoken sections gets a bit frustrating.
I agree. I distinctly heard an "s" sound after obair which made me think that the following word was sgoinneil. We're learners, not native speakers, and we shouldn't be expected to know if the speaker has a speech impediment and is indiscriminately throwing in extra consonants that aren't there!
All countries have regional dialects. You can find audio samples of American English dialects from Appalachia, the Louisiana bayou, Boston, Brooklyn, Wisconsin, Nebraska, and Southern California and see how incredibly varied pronunciations of the same words are. Suggesting anyone has speech impediments is inappropriate; the creators are clearly trying to prepare learners for as much as possible in real life interactions, something I find very useful. It takes very little time to listen to the audio a few more times, and you are still learning if you get an answer wrong.
Coming to live in Scotland, my 'learned English' was of little use and I have come to appreciate 'the living word' even if it is harder than 'class room' language. So for me it works really well to have a mix of clearly pronounced sentences, even though I doubt I'd ever hear it spoken like that 'live', and then the 'living language' as spoken by this person. The balance works for me :)
Never in a million tries would I have heard "an obair dona". This speaker is beginning to irk me mightily. My great aunt spoke fluent Doric: I would never dream of using her as an examplar of English pronunciation for beginners. Sorry, my frustration is getting the better of me now!
This sounds clear enough to me. I think you have to accept that it takes time to become accustomed to the various sounds. At first I couldn't make out many of the words but I have now been doing my daily 60 /70 points for getting on for 5 months now and I notice a big difference it doesn't take a million tries but maybe a dozen. Keep at it!
