missing sound

/aʊ/as in how

You likely treat this as two separate vowel sounds in a row, the way Hungarian handles similar sequences, rather than one continuous glide within a single syllable.

consensus
A low vowel followed by a separate, distinctly syllabified u, as if two vowel sounds in a row.
Hungarian habitA low vowel followed by a separate, distinctly syllabified u, as if two vowel sounds in a row.
One continuous glide: jaw wide open at the start, then closing while the tongue rises, retracts, and the lips round toward a single high-back finish.
English aʊOne continuous glide: jaw wide open at the start, then closing while the tongue rises, retracts, and the lips round toward a single high-back finish.
Hungarian tends to split this into two vowel sounds; English needs one unbroken glide from open 'ah' to rounded 'oo', as in 'how' and 'house'.

How natives do it

Americans start with the jaw wide open, tongue low, lips relaxed, as if saying 'ah', then glide the tongue upward and backward while the lips round, finishing near an 'oo' shape — all in one unbroken motion, spending most of the time on the open starting position.

Why it matters

Breaking this diphthong into two syllables adds an extra rhythmic beat that isn't there in English, making very common words like 'house' and 'now' sound choppier than intended. Practicing it as one smooth glide keeps these everyday words compact and natural.

How the mouth differs

Hungarian has no native diphthong of this shape; sequences like 'au' in loanwords are typically pronounced as two separate syllables (a vowel followed by a distinct u vowel) rather than a single gliding nucleus. English aʊ requires one continuous syllable that starts wide-open and low, then smoothly rises, retracts, and rounds toward a high-back position without any syllable break.

Listen for the pattern

Splitting this diphthong into two syllables, or shortening the glide into a quick tap, is usually still understood but adds an extra syllable-like beat that disrupts English rhythm and can make words like 'house' sound like they have two vowel peaks instead of one.
