The word "ozanne" is a rare surname and its spelling can be a little tricky to explain. It is pronounced as /oʊˈzæn/, with the stress on the first syllable. The "o" represents a long "o" sound and the "z" is pronounced like "z". The "a" is pronounced as "æ", which is a short "a" sound, and the "nne" is pronounced as "n". This spelling is common in French, but it is not often used in English, which may explain why it is not a familiar word to many people.
