In Greek there is only one way to pronounce the word mageia (μαγεία) = ma y i a , the y like the w in weather, and the accent at the i : http://fr.forvo.com/word/%ce%bc%ce%b1%ce%b3%ce%b5%ce%af%ce%b1/
However i think that in each language it has its own pronunciation,, example i am living in french and we call it mageϊa the g like a deep "j"
