The word "Stromain" is a bit tricky to spell because it is not a common word. The correct way to pronounce it is /ˈstroʊmeɪn/, with the stress on the first syllable. The first two letters 'str' are usually pronounced as /str/, which sounds like the word "street," but without the 'ee' sound. The 'o' in the second syllable is pronounced with a long 'o' sound like in the word "stone." The last syllable 'main' is pronounced as /meɪn/ with a long 'a' sound like in the word "rain."
