Portuguese → Cantonese
Cantonese uses 42 sounds. You already own 11 of them from Portuguese. The other 31 are the work — and 22 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 Portuguese 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.

to go out

Rhythm and pitch
The layer spelling never records, and the one that makes a correct sentence still sound foreign.
| Portuguese | Cantonese | |
|---|---|---|
| Rhythm | Stress-timed (Portugal) | Syllable-timed |
| Stress | Contrastive and written. The default is the second-to-last syllable; anything else takes an accent, and the accent also picks between open and close vowels — avó /ɔ/ is a grandmother and avô /o/ is a grandfather. | No contrastive stress; prominence comes from particles and from changed tone (變調) lifting a syllable to tone 2. |
| Pitch | No lexical tone. Intonation carries questions on its own — Portuguese changes nothing else about the sentence, so the rise is doing all the work. | lexical tone — pitch changes the word |
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 Portuguese 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.
