How to pronounce double letters		
Two different vowels should be pronounced distinctly as separate syllables, and NOT as a dipthong (so don't try to blend them together into one).
Two of the same letters should be pronounced as follows:
If the sound has no definitive start or end (true for all vowels and a few consonants like “s”), say it for approximately twice the usual length
If the sound has a definitive start or end (true for most consonants), simply say it twice.

All the examples are SOUTHERN BRITISH ENGLISH (unless otherwise indicated). Consult the IPA for the exact sound.
