Everyone seems to agree on the second word. As to the first, where's the accent?
Is it TWO syllables?:
lee-ANNE (ANNE rhymes with FAN)
lee-ON
lee-UN
LEE-anne
LEE-on
LEE-un
Or, is it a SINGLE syllable, with the "two" syllables slurred together?:
LYUN (rhymes with ONE)
LYON (rhymes with ON)
LYANNE (rhymes with FAN)
Or is the vowel before the N one of those weird, Chinese constructions that's .3156 of the way between two English vowels, a sound which no native English speaker can even hear, let alone pronounce?
