Carole asked: "What am I hearing for December Rhagfyr in the Southern course? Can't tell if it's rag-veer or rag-verr."
Geraint replied "It's more like "vir", the same vowel sound as in lid or bin to be strict bit a lot of vowel sounds are very movable from what I can hear. "
Just wanted to add that often in the north especially further west, 'y' will often sound like the Welsh 'u' ['uh' or 'ugh'].
For example 'Rhagfyr' will sound like 'RhagfUhr' rather than the southern 'ee' sound - 'RhagfEEr'.
In the north 'pry' (for fly or bug) will sound like 'pru' [prUh] rather than the southern 'prEE'. 'ty' (house) up north would sound like 'tu' [tUh] and in the south sound more like 'tEE'. In the north 'polyn' (pole) would sound like 'polun' and so on...
I've often described the Northerners use of the 'u' sound to be rather cave man like. If you want to mimic a proper Northern Pen Llyn or Caernarfon accent, beginning by exaggerating the 'uh' or 'ugh' sounds in caveman fashion would be a good starting point.
Northern speech is often slower, lower pitched and very phonetic.
Sorry, seems I've gone off on a tangent!
