I don't like the English pronunciation "LAY-bən "- it doesn't sound very nice & it sounds WAY too much like the word 'labour'. I would like it if it's said as 'Lə-BAN'.
In Sweden (no, it is not commonly used) it is pronounced LAH-ban. Most people in Sweden would probably connect it to the cute children's books about the little ghost Laban (whose sister is called Labolina).
