Cabreirés is spoken in southwestern Leon near the Galician border north of the Senabrese speaking area in Zamora to the south.
This is a clip from a video called Asina Falamos which is a documentary of the Leonese language produced in the region. The man is much easier to understand. I believe he is speaking Asturian. His Asturian is very clear. I am not sure if this is what the pure Asturian sounds like or if his is heavily influenced by Castillian. At any rate, I can only understand him about half the time even though he speaks clearly.
I can barely understand a single word of what this woman is saying. Her language sounds like she took Castillian and ran it through a Vegematic.
The last half of the video the woman is speaking most of the time. She is apparently telling a story in Leonese. The only thing that I got out of it is that this story seems to have something to do with a dog.
It is interesting that they are able to communicate even though he is speaking Asturian and she is speaking Leonese.
If you can speak Spanish or Portuguese, see how much of this you can make out.
