The correct spelling of the phrase "most proceeding" might cause some confusion due to the similarity of its two main sounds. The first sound is the "o" sound, which is represented with the symbol /əʊ/ in IPA. The second sound is the "ee" sound, represented as /iː/. The spelling of this word might, therefore, be wrongly written as "most proceding". Paying attention to the correct pronunciation of each sound can help eliminate mistakes and avoid confusion.
