I have very limited knowledge of the Finnish language, and still I'm going to give the pronunciation a go:
I-i = 'ea'-'ea' as in 'easy' (I think you kinda say it twice rather than just one long vowel)
la = 'la' as in 'last'
h = 'ch' as in 'Loch'
ti = 'ti' as in Konstantinov...
Any Finnish speakers please correct me if I'm wrong...
