The word "emfasis" is actually spelled "emphasis." This is because English usually spells the "f" sound as "ph" when it comes directly before an "i." So, the correct spelling follows this rule and includes an "e" at the beginning, an "s" at the end, and a silent "h" to indicate the "ph" sound. Using IPA phonetic transcription, the word can be spelled as /ˈɛmfəsɪs/, with the stress on the second syllable.
