site, kite, and white rhyme with each other: all end in /aɪt/. They do NOT rhyme with bauxite, because its stress is on the first syllable ('baux-', /bɔk/), not the final '-ite'. audio keeps the 'au' spelling and the /ɔː/ vowel of bauxite's first syllable; box has the same /ks/ but a different vowel (/bɒks/ in British, /bɑːks/ in American). auxiliary starts with the same 'aux' spelling but is pronounced /ɔːɡz/, not /bɔks/.
