Hear it, then say it

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

hāi

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.

hái — still

还有hái yǒu — furthermore

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

hǎi — ocean

海边hǎi biān — coast

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.

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

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.

hái

still

Second tone — rising

hǎi

ocean

Third tone — low dip

The initial: h

[x]

What the mouth does
Back of the tongue rises toward the soft palate and air scrapes through — there is friction, not just breath.
Closest English sound
Between the h in “hat” and the ch in Scottish “loch”, closer to the latter.
Where learners slip
Using the empty English h, which makes hē and ē sound alike.
Drill that fixes it
Whisper “loch” a few times, keep that scrape, then attach the vowel.

The final: -ai

[aɪ]

What the mouth does
Starts wide open on a, glides up to a short i. The first half carries the weight.
Closest English sound
The i in “eye”.
Where learners slip
Giving both halves equal length, which makes the syllable drag.
Drill that fixes it
Long a, short i: “AAA-i”, not “ah-EE”.

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.
