Strict IPA

aʊ̯

mouth /maʊ̯θ/

Standard

 aʊ 

mouth /maʊθ/

In English the IPA phonetic symbol /aʊ/ corresponds to the vowel sound in words like "mouth", "how" and "out". In some parts of the English speaking world this sound is more similar to [ʌʊ]. Other alternatives are [aw] and [ʌw]. See IPA phonetic symbol [w].

Whatever the actual sound, /aʊ/ is used as broad notation.

In strict IPA diphthongs need an inverted breve under their less prominent vowel: /aʊ̯/. However the notation we are using does not have the symbol /a/ by itself, and therefore we know that a vowel after /a/ has an implied inverted breve.
