How Do You Spell XXXI?
Pronunciation: [ɹˌə͡ʊmən θˈɜːtiwˈɒn] (IPA) 
The spelling of the word "xxxi" may seem unusual and difficult to decipher, but it follows the basic principles of phonetic transcription. In IPA notation, the "x" represents a voiceless velar fricative, similar to the "ch" sound in Scottish "loch." The two "i" letters indicate a short vowel sound, while the final "i" is pronounced as a long vowel sound. Therefore, "xxxi" is pronounced as "ḳi" or "khi," depending on the speaker's accent.
