The spelling of the word "friezing" is actually incorrect. The correct spelling is "freezing" /ˈfriːzɪŋ/. The IPA phonetic transcription for this word shows that it is pronounced with a long "e" sound /iː/ followed by a voiced "z" sound /z/. The "ng" at the end of the word is pronounced as a velar nasal /ŋ/. It is important to use the correct spelling and pronunciation of words to avoid confusion and miscommunication.
