The spelling of the word "NZHB" may seem confusing at first glance, but it can be broken down using IPA phonetic transcription. The "N" represents the nasal "n" sound, while the "Z" is a voiced fricative "z" sound. The "H" denotes a voiceless glottal fricative sound, and the "B" is pronounced as a voiced bilabial stop. So, the full pronunciation of "NZHB" would be "en-zee-aitch-bee." While the spelling may appear unusual, breaking it down using IPA can make it easier to understand and pronounce.
