The spelling of the word "NAVAO" might seem a bit tricky at first glance, but it follows the fairly consistent patterns of English spelling. Using IPA phonetic transcription, we can break it down: /nəˈvɑoʊ/. The initial "nav-" is straightforward, with the stressed short "a" sound followed by the voiced "v" and a reduced "ə". The final "-ao" is a little less predictable, but it could be roughly transcribed as a diphthong pronounced like "ow" or "o" followed by a descending tone.
