The spelling of the word "Herber" can be explained using IPA phonetic transcription. The first sound is represented by the "h" sound, followed by the "er" sound, which is pronounced as "ɜː". Together, the sounds create the first syllable "her". The second syllable is represented by the "b" sound, followed by the "er" sound once again. The "er" sound is pronounced as "ə", producing the final syllable "ber". Therefore, the correct spelling of this word is "Herber".
