The spelling of the word "VIUNI" appears to be in Swahili, a Bantu language spoken in many African countries. The IPA phonetic transcription of the word would be /vɪuːni/, with the "v" pronounced as a voiced labiodental fricative, the "i" as a close front unrounded vowel, the "u" as a close back rounded vowel, and the "n" as a voiced alveolar nasal. While the meaning of the word is not clear, the spelling follows the common Swahili pattern of alternating vowels and consonants.
