There seems to be no reference to a word called "NOHB" in English language dictionaries. However, based on the International Phonetic Alphabet (IPA) transcription, it seems that the pronunciation of "NOHB" could be /nɑb/ or /noʊb/. The first transcription would suggest a strong "a" sound followed by a "b" sound whereas the second one would indicate a long "o" sound before the "b." Regardless, without any context or definition for "NOHB," it is difficult to determine the spelling of this word.
