An Grá faoi Ghlas
This is a video series put out with Turas Teanga. They speak slowly, so everyone can easily understand. There's subtitles in Irish (though I suspect you'll find some with English ones, too).
It also showcases all three dialects, with one character having a thick Donegal one, and another using the Munster synthetic forms (though not super Munster - only Cheapas instead of Do cheapas).
Go raibh míle. Now that I've finished the tree, I'm looking for more immersive methods, and this works great. One question: Is this a show designed to be shown at schools? I'm only asking because the people seem to speak much slower than the hosts of, say, An Saol Ó Dheas on RnaG, and I'm curious if it's because some people speak slower than others or if it's intentional for the sake of understanding.
Is breá liom "Comhrá" agus éistím le hArdtráthnóna anois is aríst. Taithí éisteachta maith 'sea iad araon.
I would recommend to everybody to listen to the programme Comhrá, it is fantastic practice for understanding every dialect and they typically have strong dialectal speakers on the programme. I think it is the best intermediate listening practice available.
Ar thugais fé ndeara an nós cainte sin atá ag MTS "seaaaaaaa, bagh dad"? Bíonn a lán daoine ag magadh fé ina thaobh, ach magadh cairdiúla atá i gceist.
