Olde English may be unrecognisable now but the roots of our modern language began here.
Anglo Saxon is pronounced the same as modern English with the following exceptions:
When two vowels are together the transition is smooth and produces only one syllable.
a when followed by n or m is pronounced o, as in hot.
ea as in pear.
i when long as in machine will be spelled ig but pronounced ee.
y is a vowel and is interchangeable with i.
Double consonants are pronounced twice.
c pronounced as k if before a, o or u and at the end of words with those vowels;
pronounced ch before e, i and y and at the end of words with those vowels.
cg is pronounced j.
f is unvoiced when at the beginning of a word or following double vowels;
voiced, pronounced v in all other instances.
g as in girl when before any consonant and a, o, u and y; after n; when doubled;
pronounced y if before e and i and after r and l.
h pronounced ch as in loch if after a, o and u and after consonants;
unvoiced after e, i and y.
hw similar to modern wh, as in white.
r pronounced the American way (rolled).
sc pronounced sh as in shop.
Therefore Gulfyrian is pronounced g-u-l-v-i-r-ee-o-n.
