The word 'kuzen' is spelled with a 'k' and a 'u' followed by a 'z' and an 'e' and an 'n'. Its phonetic transcription using the International Phonetic Alphabet (IPA) is /kʊzən/. The initial 'k' sound is pronounced in the back of the mouth with the soft 'u' sound created by rounding the lips. The 'z' sound is made by vibrating the vocal cords while air passes through the narrow opening between the tongue and the upper gum line. Finally, 'en' is pronounced with a short 'e' sound followed by a nasal 'n'.
