The word "livsey" is spelled with a "v" and not a "b" because it is pronounced with the voiced labiodental fricative /v/ sound, rather than the voiced bilabial stop /b/ sound. The IPA phonetic transcription for "livsey" is /ˈlɪvzi/ , where the /v/ sound is represented by the symbol "v" and the /z/ sound is represented by the symbol "z". It is important to remember the correct spelling and pronunciation of words to effectively communicate in written and oral form.
