The word "raoux" is a bit tricky to spell because it contains a sound that is not typically present in English. In IPA phonetic transcription, "raoux" is spelled /ʁao/, with the "ao" representing a French vowel sound that does not have a direct equivalent in English. The "x" at the end is also characteristic of French spelling and indicates the final consonant is pronounced with a throaty or guttural sound. Despite its challenging spelling, "raoux" is a common French surname.
