Greenbaum is a surname that is traditionally spelled using the English alphabet. However, when transliterated into the International Phonetic Alphabet (IPA), it would be pronounced as /ɡɹiːnbɔːm/. This transcription breaks down the word into its individual phonemes, representing the sound associated with each letter. It starts with the voiced velar plosive, "g," followed by a long "ee" sound, then a voiced bilabial fricative, "m." The word ends with an unvoiced bilabial plosive, "b," and a long "aw" sound before the final voiced bilabial plosive, "m."
