Chinese Consonant Contrast Drills: Aspiration and Retroflex Practice

When you fix an initial, use the fact that the actions differ, not that the sounds are “similar.” Pick just one pair a day and practise in the order air → tongue position → reproducing it in a word. When a sound will not come, do not add force — reset the mouth position first.

Drill 1: aspirated vs unaspirated

Group	Unaspirated	Aspirated	Practice words
Lips	b	p	爸爸 (bàba, “dad”) / 怕 (pà, “to fear”)
Tongue tip	d	t	到 (dào, “to arrive”) / 套 (tào, “cover, set”)
Back of tongue	g	k	高 (gāo, “tall”) / 靠 (kào, “to lean on”)

Hang a tissue at your lips. On an aspirated sound, the air continues enough to move the paper right after the consonant. On an unaspirated one, hold the air and release it short. Judge only by whether the paper moves, not by any voiced/voiceless feeling from your own language.

Drill 2: three tongue positions

Line up 知 (zhī, “to know”), 七 (qī, “seven”), 子 (zǐ, “child”) with the same vowel. 知 (zhī) curls the tongue tip back; 七 (qī) keeps the tongue flat and forward; 子 (zǐ) puts the tongue tip near the back of the front teeth. Make each position silently in this order first, then add sound.

Group	Position	Air comparison
zh/ch/sh	tongue tip curled slightly back	only ch has strong air
j/q/x	tongue flat and forward	only q has strong air
z/c/s	tongue tip near the front teeth	only c has strong air

Drill 3: check it does not collapse in words

Once single sounds work, go to two syllables. Pick words like 知道 (zhīdào, “to know”), 起床 (qǐchuáng, “to get up”), 自己 (zìjǐ, “oneself”), and record whether the tongue position and air survive once a tone is added. If it collapses in words but not alone, the problem may be tone or speed, not the articulator. Say it once at half speed, then return to normal.

You do not have to finish all three groups in one session. For the first week, just rotate b/p, zh/ch/sh, and j/q/x. Recheck the position diagrams in mastering the difficult sounds.
