Hear it, then say it

Tap play for each tone, then record yourself — your pitch curve is drawn on top of the model.

dūn

This tone exists, but no HSK 1–3 word uses it yet — practise the sound on its own.

Hold one steady high note, like a doctor’s “aaah”. English has no flat pitch, so it will feel unnaturally robotic — that is correct.

dùn — to stop

Start at the top and drop fast, like a firm “No!”. Short and decisive.

The initial: d

[t]

What the mouth does
Tongue tip on the ridge behind the upper teeth, released with no puff of air.
Closest English sound
The t in “stop”, not the d in “dog”.
Where learners slip
Voicing it like English d — again fine alone, fatal for the d/t contrast at speed.
Drill that fixes it
Say “stop… top”, then strip off the s: that first sound is Mandarin d.

The final: -un

[wən]

What the mouth does
Written un, pronounced uen — a schwa hides in the middle. After j, q, x, y it is ün instead: lips rounded, tongue front.
Closest English sound
The “won” in “wonder”.
Where learners slip
Reading it as a plain “oon”.
Drill that fixes it
kùn is “kwun”, but jūn is “jün”. The initial decides.
