The correct spelling of the phrase "all live thing" is actually "all living thing". The addition of the "ing" is important to ensure proper grammar. The correct pronunciation using International Phonetic Alphabet (IPA) is /ɔl ˈlɪvɪŋ θɪŋ/. The first syllable is pronounced as "all", but with a shorter "a" sound. The word "living" is pronounced with emphasis on the first syllable and a long "i" sound, while "thing" is pronounced with a soft "th" sound and a short "i".
