The correct spelling of the name "Mirriam" is usually spelled with two "r's" and two "m's" - 'Mɪr.ɪ.əm.' The first syllable 'Mɪr' is pronounced with a short "i" sound and the second syllable 'ɪ' has a short "i" as well. The IPA transcription for the final syllable 'əm' is an unstressed, 'schwa' sound. It is always important to spell names accurately because it identifies people and can affect how they are perceived.
