You can hear the pronunciation using this Finnish speech synthesizer:
http://www.mikropuhe.com/demo.asp (Type the word you want in the text field and click "Kuuntele puhe.")
It's three syllables: MIE-lik-ki.
In the first syllable,
ie is a diphthong--a short
i followed by a short
e (ih-eh). It's kind of like the English diphthong AY (which is a short
e followed by a short
i) reversed.
The second syllable is pronounced like the English word "lick."
The
i in the third syllable is short--like in "kick."
Both k's are pronounced. (Think of English words like boo
kkeeper or bla
ck cat.)
Was that complicated enough? :)
