The word "IPHASE" is pronounced as /aɪfeɪz/ in IPA phonetic transcription. The first syllable "I" sounds like the long "i" sound in the word "eye". The second syllable "PHASE" is pronounced as /feɪz/ with the "f" and "s" sounds. This spelling follows the English language's tendency to use the letter "i" to represent the long "i" sound and adding "ph" instead of "f" to represent the "f" sound in some words.
