Just read this, then checked around office making sure everyone is away, then tried pronouncing Lletya. :L
Ll is a sound with no English equivalent. It is formed by pronouncing L with a slight escape of air around the tongue, and sounds like thl or shl with the leading th/sh very soft. Try saying whistle with a lisp, as whithle.

Thl-e-t- ok..
y has two different sounds. In one-syllable words (llyn), and in the last syllable of polysyllabic words (estyn), it is a shortened EE sound as at the end of happy. (Note the different sound in ywy, however). In other contexts (in non-final syllables of polysyllabic words) it is pronounced as the obscure vowel schwa, as in the first syllable of the English word about (e.g. ystyr, pronounced uh s t ii r, where uh represents schwa).
The preceding rules for y apply to South Welsh accents. In areas of North Wales, the non-schwa pronunciation of y is less like English EE and more of a guttural sound, formed further back in the mouth.
