Hear it, then say it

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

一yī — one

一起yī qǐ — in the same place

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

— model— your pitch· Shape, not score. Scoring lives in the app.

移yí

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

Rise from the middle to the top, like the English question “huh?”. The rise must reach the top, not stall halfway.

— model— your pitch· Shape, not score. Scoring lives in the app.

已yǐ

已经yǐ jīng — already

In real speech this tone is mostly LOW, not a full dip-and-rise. Drop to the bottom of your range and stay there; the rise only appears when the syllable is said alone or at the end of a phrase.

亿yì — 100 million

意思yì si — idea

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

— model— your pitch· Shape, not score. Scoring lives in the app.

宜yi

便宜pián yi — cheap

No pitch shape of its own: short, light, and pitched by whatever came before it.

Same sounds, different word

These words are built from the exact same consonant and vowel. Only the tone tells them apart — which is why tones are not decoration.

yī

one

First tone — high and flat

yǐ

already

Third tone — low dip

yì

100 million

Fourth tone — sharp fall

The initial: y

[j]

What the mouth does: Not a real consonant — a spelling device. Written when i, ü or a following vowel starts the syllable.
Closest English sound: The y in “yes”, gliding straight into the vowel.
Where learners slip: Treating y as a separate sound and inserting a pause after it.
Drill that fixes it: Glide, do not stop: yī is one smooth sound, not “y + i”.

The final: -i

[i]

What the mouth does: Tongue high and front, lips spread. Long and tense.
Closest English sound: The ee in “see”, without the slight glide English adds.
Where learners slip: Shortening it to the i of “sit”.
Drill that fixes it: Smile hard and hold the vowel steady — no drift at the end.

Tone change you need to know

Two third tones in a row

When a third tone is followed by another third tone, the first one is pronounced as a second tone. 你好 is written nǐ hǎo but said “ní hǎo”. The writing never changes — only the mouth does.

Third tone before any other tone. Before a first, second or fourth tone, the third tone loses its rise entirely and stays low. This “half third” is what you hear in almost all real sentences.
