The spelling of "raborn" can seem confusing, but once you break it down with IPA phonetic transcription, it becomes clear. The word is pronounced /rəˈbɔrn/ with the stress on the second syllable. The "r" at the beginning is followed by a schwa sound (/ə/) and then the stressed syllable has a short "o" sound (/ɔ/). The final syllable includes an "n" sound followed by a silent "e". To remember the spelling, it may be helpful to think of it in syllables: ra-born.
