The word "BAUA" is spelt using four phonemes, represented in the International Phonetic Alphabet as /baʊə/. The first sound, /b/, is a voiced bilabial stop, produced by closing the lips together and releasing a burst of air. The second sound, /aʊ/, is a diphthong that begins with an open back unrounded vowel /a/ and transitions to a close-mid back rounded vowel /ʊ/. The final sound, /ə/, is a schwa, an unstressed and neutral vowel sound. Together, these phonemes create the spelling of "BAUA".
