This is an extremely interesting lect being spoken here. It looks more like Furniello spoken in the Fornela Valley region around where Asturias, Leon and Galicia all come together. The language itself looks something like Berciano, Western Asturian or Eastern Galician.
Here are some of my notes on this language:
Forniellu is spoken in the Fornela Valley in and around the towns of Guimara, Peranzanes, and Transcastro. It is a mixture of Leonese, Asturian, Galician and Castillian. It is probably not intelligible with Galician. It is difficult to place this lect. Formally it is considered to be transitional between Leonese and Galician, but it is more likely to be Leonese transitional to Galician. This is sometimes said to be part of Berciano. Best characterized as Leonese. Intelligibility with Fabieru Berciano speakers from nearby Fabero nine miles to the south is excellent.
The people in this area say that they speak Galician, but the truth is they are really speaking Leonese or Berciano. When Berciano speakers go to Galicia, they are not understood, so Berciano is not a type of Galician.
I was utterly lost with this old lady’s story. I could hear a few words now and then, but it wasn’t enough to figure out what she was talking about. After seven minutes, I did not have the slightest idea of what she was talking about. You are listening to it and thinking, “You know, this really does sound like Spanish…” but then you still can’t seem to make out of a word of it. To my untrained ear, it also seems to sound like some sort of a Portuguese-Spanish mix.
If you can speak Spanish or Portuguese, see how much Furniellu you can understand.
