In Brazil, it may be also pronounced as "ô-kei". In Portugal, it is used with its Portuguese pronunciation and sounds something like "ókâi" (similar to the English pronunciation but with the "ó" sounding like the "o" in "lost" or "top"), or even as 'oh-kapa', from the letters O ('ó') and K ('capa'). In Spain it's much less common than in Latin American countries (words such as "vale" or "de acuerdo" are preferred) but it may still be heard.
