The spelling of the word "Bibbey" can be explained using the International Phonetic Alphabet (IPA). The initial sound "b" is voiced and produced by bringing the lips together and forcing air through the vocal cords. The vowel sound "i" is a short and closed sound, pronounced by raising the front of the tongue towards the roof of the mouth. The consonant sound "b" is repeated before closing the word with the sound "ey", which is produced by rounding the lips and releasing air while gradually closing the mouth.
