zāi

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.

The initial: z

[ts]

What the mouth does
Tongue tip at the back of the upper teeth, released as one tight “ts” with no puff.
Closest English sound
The ds in “kids”, but at the start of a syllable — a position English never allows.
Where learners slip
Reading z as English “zzz”, which is a different sound entirely.
Drill that fixes it
Say “kids”, isolate the “ds”, then put it in front of a vowel: ds-a → za.

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.
