How Do You Spell XXXXX?
Pronunciation: [ˌɛksˌɛksˈɛksˌɛksˈɛks] (IPA) 
The spelling of the word "xxxxx" is somewhat tricky to decipher since it could refer to a number of different words. However, based on the assumption that the word is pronounced with the English language, it's safe to assume that its IPA phonetic transcription would be something like /ɪks/ or /ɛks/. This is because the sound of "x" in English is typically represented by the letters "ks" or "gs," and usually has a hard sound rather than a soft "z" sound as in other languages.
