The word "avise" is an archaic form of the verb "advise." Its spelling includes the letter "s" instead of the modern "z" as in "advise." In IPA phonetic transcription, "avise" is pronounced /əˈvaɪz/. The "a" sound is pronounced as the schwa, the "v" sound is the voiced labiodental fricative, the "i" sound is the long vowel and the "z" sound at the end is pronounced as the voiced alveolar fricative. The spelling was commonly utilized in Middle English and early Modern English but is now obsolete.
