Mandarin Chinese → Cantonese
Cantonese uses 42 sounds. You already own 18 of them from Mandarin Chinese. The other 24 are the work — and 19 of those are the dangerous kind: close enough to something you already say that you will substitute them without hearing yourself do it.
The silent swaps
Your mouth has something close enough to reach for. These survive for years precisely because they sound right to you — the fix is hearing the difference first, not trying harder.

Words you may say identically
Two or more Cantonese sounds landing on one sound of yours. Until the ear separates them, the mouth cannot — which is what the ear trainer is for.
Genuinely new
Nothing in Mandarin Chinese sits close to these. They sound foreign in your mouth — which is the good news: you can hear that you are not saying them yet.
good
Closest thing you own: — but labiodental → glottal.
I
Closest thing you own: — but close-mid → open-mid, longer.
to open
Closest thing you own: — but close-mid → open-mid, longer.
small
Closest thing you own: — but it glides, yours would hold still, longer.
cup
Closest thing you own: — but it glides, yours would hold still, longer.
Rhythm and pitch
The layer spelling never records, and the one that makes a correct sentence still sound foreign.
| Mandarin Chinese | Cantonese | |
|---|---|---|
| Stress | Stress is a matter of length and clarity rather than pitch: a stressed syllable holds its full tone, an unstressed one goes neutral and short. | No contrastive stress; prominence comes from particles and from changed tone (變調) lifting a syllable to tone 2. |
What you have that Cantonese doesn't
24 sounds with no job in Cantonese. They are not mistakes — but they are where an accent leaks in, because a sound you own is easy to use when a hard one is due.
The honest caveat
This is a prediction from the shape of two sound systems, not a recording of you. It says what your inventory makes likely — it cannot know that your Mandarin Chinese has a regional variety that already owns one of these, or that you learned Cantonese from someone whose accent you copied. A teacher listening to you beats it. Use it to know what to listen for.
