The correct spelling of "Amison" is /əˈmɪsən/. The first syllable is pronounced with the neutral vowel sound represented by /ə/. The second syllable is pronounced with the short "i" sound represented by /ɪ/. The final syllable is pronounced with the neutral vowel sound again, and is spelled with the letter "o" rather than "u", which would indicate a different vowel sound. The IPA transcription helps to clarify the precise pronunciation of the word to avoid any confusion.
