Given the recent political developments in Europe, the word refugee is now used much more often by non-native speakers. Because most of them are not aware of the correct pronunciation, let me mention it here.
The most obvious mistake is to stress the word on the first syllable. Instead, refugee is stressed on the last syllable, as apparent from the phonetic spelling (‘ indicates stress)
You can also clearly hear the stress on the last syllable here. (In the case of German speakers, putting the stress on the first syllable may be a classified as a pronunciation false friend related to the German word Flüchtling.)
Minor but also quite common mistakes are the pronunciation of the letter g as [tʃ] instead of [dʃ] (compare China and John), and the short pronunciation of the -ee ending (the : in i: indicates a long pronunciation).
