Yes that was a hard, if not impossible, one to decipher "air" seemed to be "air" brushed out. What I hear is "Ta ist snaw" .A heavy Dublin accent there I think ! I was listening to the Irish Language program on Radio Ulster and there was a guy speaking in a strong Ulster accent. I could only get the word" agus" which was repeated many times. Is there any equivalent to the Queens English in Ireland I suppose it would be called Uachtaran Gaeilge !!! If not has anybody got an enigma machine ??
About six times in my life and have heard people like Ronnie Drew (GRHS) Bob Geldof and other famous ones talk on the media but I am probably wrong about that anyway !!! I find the audio on this course not always clear and I keep having to repeat it.It seems like whole words disappear from the text sometimes yet sometimes it is fine.Depends on the speaker I suppose !
There is only one speaker on Duolingo, as far as I'm aware. The recordings would have taken a considerable time to complete, so there are differences between the same word in different exercises, because they were recorded during different sessions, or at different times during a session, or because the words before and after a particular word might influence things somewhat.
As for Dublin accents, comparing Ronnie Drew to Bob Geldof is a bit like comparing chalk and cheese - they both have very different accents, and Geldof's, in particular, is not what most people think of when you say "a Dublin accent" - though strictly speaking, his London accent still retains recognizable features of one of at least 5 or 6 quite distinct accents that are from different parts, and different generations, of Dublin.
None of the accents that are typical of Dublin and it's suburbs pronounce "r" the way this speaker pronounces air.
